Kirby's Star Stacker is a 1997 puzzle video game developed by HAL Laboratory and published by Nintendo for the Game Boy.

It received a remake for the Super Famicom in Japan.

Kirby's Star Stacker is similar in many respects to other falling block puzzle games that were around at the time of its release, most notably Soldam. The goal of the game is to earn as many stars possible by matching pairs of blocks (also referred to as friends in-game) that fall from the top of the play area. There are three types of blocks, all based on Kirby's friends from Kirby's Dream Land 2: Rick the hamster, Coo the owl, and Kine the fish. Stars are scored by sandwiching the stars between two matching blocks. When stars are scored, they disappear from the play area along with the pair of blocks enclosing them. The game is lost when the falling blocks reach the top of the play area (middle rows only), so it is critical to eliminate as many blocks as possible by scoring stars.
