is a 1983 edutainment platform video game developed and published by Nintendo for the Nintendo Entertainment System. It is a spin-off of the 1982 arcade game Donkey Kong Jr. In the game, players control Donkey Kong Jr. as he solves math problems set up by his father Donkey Kong.

It is the only game in the Education Series of NES games in North America, owing to the game's lack of success. It was made available in various forms, including in the 2002 GameCube video game Animal Crossing and on the Virtual Console services for Wii and Wii U in 2007 and 2014 respectively, and in 2024 for the Nintendo Classics service. Donkey Kong Jr. Math was a critical and commercial failure. It has received criticism from several publications including IGN staff, who called it one of the worst Virtual Console games.

Bruce Lowry, Nintendo of America’s vice president of sales from 1981 to 1986, referred to it as “the worst game we ever sold.”

The game features two modes, one single-player and the allowing for one to two players. It was published by Nintendo for the Family Computer (Famicom) and Nintendo Entertainment System (NES). A lack of success by the game was attributed by a Nintendo spokesman to be the reason Nintendo did not make more educational titles. In August 1995, the Sharp multicart was re-released separately from the C1 Famicom TV. Donkey Kong Jr. Math was re-released on the Wii's Virtual Console in Japan on March 27, 2007, Europe and Australia on April 20, and in North America on September 3.
