The Heroic Quest of the Valiant Prince Ivandoe (often shortened to Prince Ivandoe or just Ivandoe) is an animated television series created by Eva Lee Wallberg and Christian Bøving-Andersen and co-created by Daniel Lennard for Cartoon Network. It began airing on Cartoon Network in Denmark, Finland, Iceland, Norway, and Sweden on November 20, 2017. The series is the second to be produced by Cartoon Network Studios Europe (now Hanna-Barbera Studios Europe). It is a parody of the 1820 British novel Ivanhoe by Sir Walter Scott. The shorts take on a style very reminiscent of Studios Europe's earlier cartoon, The Amazing World of Gumball, featuring animation created with a variety of different sources.
On June 15, 2020, it was announced that Cartoon Network had ordered a long-form series consisting of 40 11-minute episodes. The series made its premiere at the Annecy Festival on June 14, 2022.
