Klonoa Beach Volleyball is a sports spin-off from Namco's Klonoa video game series released as a budget title in the last few years of the PlayStation's commercial lifespan. Its release was limited to Japan and Europe only. It features characters from the PlayStation and Game Boy Advance games in the series, and can most likely be considered non-canonical in this sense, as many of these characters would never meet in the main story.

This is also the first Klonoa title to feature a multiplayer mode, allowing up to four players to compete in pairs against the other team. The game also allows for controller sharing, should the players not be in possession of a multi-tap.
