Jack Champion was born on November 16, 2004 and is a native of Blacksburg, Virginia. He was raised by his mother, a microbiologist. He has credited her for encouraging his interest in acting. He began acting at age eight, starting in school theatre and eventually began working in short films. In 2015, he had a small role in the documentary series American Genius.
In 2017, Champion booked a screen test to join the cast of James Cameron's science fiction film '. Before he was cast in the role, he filmed a small part in the superhero film ' (2019) as a kid on a bicycle. He also had a leading role in the horror film The Night Sitter (2018). Champion booked his part in Avatar at age 12, after four months of extensive auditions. He was cast as Miles Socorro, a human teenager living amongst Na'vis on Pandora. The nature of Champion's role meant that he had to film all his scenes twice, once as a reference for his co-stars, including Sam Worthington, Zoe Saldaña and Sigourney Weaver, and another to actually film the actor in live-action; his work involved two years of performance capture on a soundstage, followed by two and a half years of filming the same scenes in live-action in New Zealand. He learned freediving and scuba diving for scenes that were filmed underwater. After five years of production, the film was released in 2022, after Champion turned 18. It earned over $2 billion worldwide, becoming the third highest-grossing film of all time. Champion concurrently shot for the sequel, ', which released in 2025, and portions of Avatar 4, which will release in 2029. This was primarily done so that Champion would not age out of his role.
In 2023, Champion appeared alongside an ensemble cast in the slasher film Scream VI, playing the part of Ethan Landry. In contrast to his experience of working on Avatar, he described filming Scream VI as a "really fun summer vacation". He then played the son of star Liam Neeson's character in the action thriller Retribution, a remake of the 2015 Spanish film of the same name. Champion next appeared alongside an ensemble cast in Anna Boden and Ryan Fleck's 1980s-set action drama film Freaky Tales, which premiered at the 2024 Sundance Film Festival.
In addition to the Avatar sequels, Champion next starred in the family drama Everything's Going to Be Great and in the action thriller Trap House.
