Puyo Pop Fever is a 2003 puzzle video game developed by Sonic Team and published by Sega. It is the fifth main installment in the Puyo Puyo series, and the second Puyo Puyo game to be programmed by Sonic Team after Puyo Pop (which was released just after the series' original developer, Compile, went bankrupt). This was the start of what can be considered a reboot of the Puyo Puyo franchise, with this entry's plot revolving around Professor Accord losing her flying cane.

Sega, which acquired the series' character rights from Compile in 1998, and eventually the full rights in 2001, published all the Japanese releases of the game, and also published the arcade and GameCube versions internationally. The game was scarcely released internationally, and certain versions were released by other publishers in those areas.
