Warriors, also known as Warrior Cats, is a novel series about the adventures and drama of multiple Clans of feral cats. Warriors is published by HarperCollins and written by a team collectively known as Erin Hunter. The concept of the series was developed by Victoria Holmes, who wrote the storylines until her retirement in 2017.
There is an extensive list of works in the Warriors series. There are currently nine sub-series ("arcs"), each containing six books: The Prophecies Begin, ', ', ', Dawn of the Clans, A Vision of Shadows, The Broken Code, ', and '. In addition to the main series, "Super Edition" novels, several novella trilogies, several volumes of original English-language manga, and graphic novels have been published. A website, a mobile app, and an official Roblox game also exist.
Warriors has received mixed reviews from critics, who praised the plotlines and suspense, but criticized the large character cast. Warriors has been nominated for multiple awards, and has a dedicated online fanbase. The novels have a variety of themes, from politics to religion and economics. Warriors has been translated into 30 languages, and has sold over 30 million copies worldwide.
In 2001, publisher HarperCollins asked editor Victoria Holmes to write a fantasy novel about cats. Holmes enlisted the help of Kate Cary, and together they came up with enough content for a six-novel series. Cary wrote the first two novels in , Into the Wild and Fire and Ice. After the first two novels, Holmes had to "speed up" to maintain the publishing schedule; Cherith Baldry joined the team and wrote the third novel, Forest of Secrets. Cary wrote the fourth novel, then Baldry wrote the fifth and the sixth. During the writing process, Holmes came up with "the detailed storyline and the characters" for the next novels. When Holmes finished creating a storyline, Tui T. Sutherland assisted in editing until both agreed on the storyline, and it could be sent to Cary and Baldry to write the final novel. Holmes would then edit the finished novels to "keep continuity", before it would be published under the pen name Erin Hunter.
Following a cancer diagnosis in 2017, Holmes stepped back from her involvement with the Erin Hunter team. After 21 years, Cary left the Erin Hunter team to focus on "other projects". The more recent books' storylines are written by five editors known as the "Story Team".
The authors have named several other authors as sources of inspiration when writing the novels. In an interview, Baldry stated that the writers who influenced her the most are Tolkien, C. S. Lewis, and Ursula K. Le Guin. According to the official website, other authors who have inspired the writers include Enid Blyton, Lucy Daniels, Ellis Peters, Tess Gerritsen, Kate Ellis, Lisa Gardiner, and Meg Cabot.
Holmes has cited the New Forest in southern England as inspiration for the forest where the first arc takes place, as it has a variety of different environments. She also cited the films First Blood and The Avengers as a source of inspiration.
The Warriors universe centers around feral cats who initially reside in a forest, and later, around a lake. The cats are split into five groups called Clans: ThunderClan, WindClan, RiverClan, ShadowClan, and SkyClan. Each Clan has adapted to its own terrain, and some are named after their specialized abilities. Relationships between different Clans are usually tense, and the Clans often come into conflict with one another. However, the Clans also sometimes show concern for each other; the idea of one Clan being destroyed usually causes deep distress and prompts urgent action on behalf of all Clans. The Clans have a unique naming and hierarchy system, in that their names are determined by their rank in the Clan.
The Clan cats have a faith system based on the concept of StarClan, a group of the spirits of the Clans' deceased ancestors, who provide prophetic guidance to the living Clan cats. After death, the spirits of most Clan cats join StarClan and reside in a paradisaical forest similar to Heaven. In addition to StarClan, there exists the Dark Forest, also known as the Place of No Stars, which takes the form of a never-ending forest, similar to Hell. The spirits of cats who caused great pain and suffering to others while alive reside there as a form of punishment.
Cats who live outside of the Clans are categorized into three groups: housecats, who are called "kittypets" by Clan cats and generally do not pose a threat; loners, stray cats who live outside of the Clan territories and who sometimes assist the Clans; and rogues, who may live alone or in groups, and may intend to cause harm to the Clans.

Several trilogies of original English-language manga were produced by HarperCollins and Tokyopop. The manga were intended to be "side stories", shorter than regular manga due to publishing schedule restrictions. Short manga sections have been included in the last pages of some Warriors novels as well. With the shutdown of Tokyopop in 2011, subsequent manga volumes, starting with A Shadow in RiverClan, have been published under the name HarperAlley. Additionally, the original Tokyopop black-and-white manga have been republished in full color as standalone volumes. All manga were illustrated by James L. Barry, with the exception of The Rise of Scourge (illustrated by Bettina M. Kurkoski and Danielle Weires) and Tigerstar and Sasha (illustrated by Don Hudson).
On 28 September 2023, the official Warriors website announced that the first arc, ', would be adapted into graphic novels by Natalie Riess and Sara Goetter. The graphic novels were published between 2024 and 2025, and adapt The Prophecies Begin into three volumes. The second arc, ', will be adapted into graphic novels by Gibson Twist and Sammy Savos.
The first Warriors novel, Into the Wild, was generally well-received, with Booklist calling it "spine-tingling", Sally Estes of the American Library Association calling it "thoroughly engrossing", and Publishers Weekly calling it an "exciting ... action-packed adventure". Mary Alpert of School Library Journal praised the authors for "creating an intriguing world ... and an engaging young hero". Janice M. Del Negro, writing for The Bulletin of the Center for Children's Books, criticized the characters and imagined world as being "neither ... consistent nor compelling". Cindy Welch, writing for Booklist, stated about Rising Storm that "Hunter once again tells a good, suspenseful adventure story", and "teens may find their own journey toward adulthood echoed in the protagonist's struggles and self-doubts".
The large number of characters involved in the series has often been seen as a negative point; though one reviewer compared the "huge cast" to that of a Greek drama, others wrote that it was "hard to follow", and "a little confusing". The characters have also been criticized as being "somewhat flat" and "limited essentially to each individual's function within the Clan".
Booklist stated that the cats in the series are "true to their feline nature"; Kirkus Reviews commented that the books will "leave readers eyeing Puss a bit nervously", and wondering "what dreams of grandeur may haunt the family cat". However, this realism also means that the series contains a relatively large amount of violence, with Sharon Rawlings writing for School Library Journal stating that it is "not for the faint of heart". Several critics have compared Warriors to Brian Jacques's Redwall series, though Alpert commented that it was "not as elegantly written". The New York Times called the series a "hit with young readers", specifically because of its "sprawling universe", and the series appeared on the New York Times Best Seller list for a total of 119 weeks, as of 23 November 2014.
The manga has also earned praise: a reviewer for Children's Bookwatch wrote that Into the Woods "ends on a tense cliffhanger, leaving the reader in anxious anticipation for more [...] Into the Woods is especially recommended for cat lovers everywhere." Its sequel, Escape from the Forest, was also well reviewed: a reviewer for Publishers Weekly said that readers would benefit from reading about Sasha leaving the powerful Tigerstar due to his "growing violence". The art was also praised, with the reviewer writing that "Hudson's artwork brings Sasha's emotional journey to life, showing each moment of fear, anxiety, contentment, and joy. The cat's-eye perspective of many of the panels, in addition, add a dramatic, energizing element to the book." The reviewer also wrote that "a twist at the end will leave fans eager for the next installment of Sasha's saga", and that the book would appeal to young adults trying to find their place in the world. Lisa Goldstein writing for School Library Journal also gave the book a positive review, writing that the plot would attract new fans and appeal to old fans. Goldstein also wrote that "though the cover claims that this is a 'manga,' the straightforward illustrations are drawn in a simple, realistic style." The New Prophecy audiobooks are spoken by Nanette Savard; a reviewer for AudioFile wrote that "[h]er dazzling variety of voices (and tonal variety within voices) astonishes", and another that "[h]er narration is crisp and clear, and she knows how amplify the drama by building tension".
The graphic novel adaptations of The Prophecies Begin have received both praise and criticism from Kirkus Reviews. A review of Volume 1 wrote that the "vivid colors, dramatic action sequences, and appealingly expressive feline faces will grab readers' attention". A review of Volume 2 criticised the difficulty of visually recognising characters, "particularly since the illustrators admit to adding a few extras". A review of Volume 3 wrote that "the visual format suits the violent, dramatic storyline".
Into the Wild was nominated for the Pacific Northwest Library Association's 2006 Young Reader's Choice Awards, but lost to Christopher Paolini's Eragon; it was also listed on Booklists top ten fantasy books for youth in 2003. The Sight was nominated for the best Middle Readers book in Amazon's Best Books of the Year (2007) and placed sixth out of the ten nominees, with six percent of the total votes. In 2006, Warriors also received an honourable mention for the best book series for Publishers Weekly "On the Cuff" awards.
Abby Hargreaves of Book Riot wrote that Warriors could be "the Redwall of the next generation" and is also comparable to The Chronicles of Narnia. One of the authors behind Erin Hunter, Tui T. Sutherland, went on to write Wings of Fire, a similar book series about dragons. Warriors has a notably large fanbase on the social media platform YouTube, with fans posting animations based on the series as early as 2007; a fan has attempted to produce an animated series based on Warriors, titled SSS Warrior Cats. In a 2010 interview, Holmes stated that there is "a lot of role playing" online, and readers "create their own characters that interact with each other online in role-playing games". Scratch users create Warriors-inspired video games, such as character designing games and adventure games. The 2017 video game Cattails "takes some inspiration" from a fan-made Warriors game, according to lead developer Tyler Thompson.
When Holmes wrote the storyline, she included themes such as "death, religion, politics, betrayal, doomed romance, [and] prejudice". She has stated that "the characters do need to tackle issues that can be identified in twenty-first century life", citing Firestar's journey to be accepted in ThunderClan and Ravenpaw's shyness when in groups as examples.
A reviewer for Publishers Weekly wrote that friendship and responsibility are taught to characters in the novels. Charlotte Ahlin writing for Bustle stated that Warriors are "wildly complex novels filled with political intrigue, religious warfare, forbidden love, and violent cat death", also calling it a "multi-layer epic". Resilience is a theme often presented in the novels, as the Clans help each other when necessary, such as in Dawn. Warriors "explores themes of political and regional economics", such as when ThunderClan help return WindClan to their forest home, resulting in a political alliance. Territory is presented through "human and animalistic concepts". Thus, loyalty to the Clan is also a theme. Sarah Fimm, writing for The Mary Sue, stated that Warriors has themes like "complex political strife". They also wrote that Warriors are "[t]ales of intrigue [...] and deep feline spirituality". Other themes include nature vs. nurture, and "caring and community". A review by Kirkus Reviews wrote that Exile from ShadowClan makes readers "ponder larger questions about violence, power, codes of law, community values, metaphysics, and individuals finding their niches".
The Warriors website previously featured Warriors screensavers, videos on topics such as the process of writing a manga book, and quizzes. In addition, there were browser-based games including the The New Prophecy Quest and the Warriors Adventure Game. An online game for the website was planned for release in 2010 but was never finished. The website was later redesigned. The redesigned website features a character creation game, a character family tree, and art challenges.
In November 2016, David Heyman announced that Alibaba Pictures had bought the production rights for a film adaptation of Warriors.
