The PlayStation Portable (PSP) is a handheld device manufactured by Sony starting in 2004 in Japan and 2005 worldwide. Tag a question with this tag only if you are discussing a platform-specific feature of a game, or if you have questions about PSP hardware.

The PSP uses a proprietary disc format called the Universal Media Disc (UMD) and supports saving to Sony MemoryStick flash memory cards. Some revisions of the PSP do not support disc media, and instead download their games directly to the memory device from Sony's servers.
