Death Jr. is a 2005 video game for the PlayStation Portable. The PSP iteration was the first PSP game shown publicly and advertised as a killer-app. It was released to a mixed reception and noted for numerous problems about the camera, gameplay and uninspiring graphics, but was praised for its Tim Burton-esque themes and quirky characters. Slightly better received was the comic book adaptation by Gary Whitta and Ted Naifeh, which includes two three-issue miniseries. The game was followed by Death Jr. II: Root of Evil in 2006 and Death Jr. and the Science Fair of Doom in 2007.

Death Jr. was conceived during experiments with the engine of the cancelled game Prime 8, a planned spin-off to the Spyro The Dragon series.
