Donkey Kong Country 2: Diddy's Kong Quest is a platform video game developed by Rare and published by Nintendo for the Super Nintendo Entertainment System (SNES). It was released on 21 November 1995 in Japan, and in December 1995 in North America and Europe. It is the second instalment of the Donkey Kong Country series and serves as a direct sequel to Donkey Kong Country.

The story revolves around Diddy Kong and his close friend, Dixie Kong, who try to rescue Donkey Kong after he is abducted by King K. Rool. The game is set on Crocodile Isle, with eight worlds of varying environments, totaling 52 levels. The game utilises the same Silicon Graphics (SGI) technology from the original, which features the use of pre-rendered 3D imagery. Diddy's Kong Quest received critical acclaim, being widely regarded as one of the greatest 2D platformers ever made. Praise was directed at its graphics, gameplay, and soundtrack. It was the second best-selling game of 1995, the sixth best-selling game on the SNES, and the highest selling SNES title to not be packaged with the system.
