What is the name of Kirby's home planet?

Kirby’s home planet is Pop Star, commonly written as Planet Popstar. It is the yellow, star-shaped world where Kirby lives and where many of his adventures begin. Dream Land is a region on that planet, not the planet’s name itself.

The Kirby series centers on Kirby’s efforts to protect Planet Popstar from threats ranging from greedy rivals to cosmic villains. In many games, Kirby starts in or near Dream Land before traveling across other parts of the planet and beyond. The setting combines peaceful landscapes, whimsical villages, castles, forests, and outer-space locations.

The wording can cause confusion because Dream Land is so closely associated with Kirby. The original Kirby’s Dream Land made that location especially prominent, and King Dedede is often described as Dream Land’s ruler. However, the broader setting is Planet Popstar. Other Nintendo locations, such as Hyrule and the Mushroom Kingdom, belong to The Legend of Zelda and Mario franchises respectively.
