Catherine[c] is a puzzle video game developed by Atlus. The game was released for the PlayStation 3 and Xbox 360 in Japan and North America in 2011, in PAL regions by Deep Silver in 2012, and for Microsoft Windows by Sega in 2019. A re-release with additional content, titled Catherine: Full Body, was released in 2019 for the PlayStation 4 worldwide and for the PlayStation Vita only in Japan, and a Nintendo Switch version released worldwide in 2020.

The story follows Vincent Brooks, a man who is beset by supernatural nightmares while torn between his feelings for his longtime girlfriend Katherine and the similarly named beauty Catherine. The gameplay is divided between the daytime, where Vincent interacts with the characters in a social simulation, and his dreams where he must navigate three-dimensional towers through combined platforming and puzzle-solving. The game's ending is affected by choices made by Vincent over the course of the story.
