The PlayStation Portable (PSP) is a handheld game console developed and marketed by Sony Computer Entertainment. It was first released in Japan on December 12, 2004, in North America on March 24, 2005, and in PAL regions on September 1, 2005, and is the first handheld installment in the PlayStation line of consoles. As a seventh generation console it competed with the Nintendo DS.

The PSP was received positively by critics, and sold over 80 million units during its ten-year lifetime. Several models of the console were released, before the PSP line was succeeded by the PlayStation Vita, released in Japan in 2011 and worldwide a year later. The Vita has backward compatibility with PSP games that were released on the PlayStation Network through the PlayStation Store, which became the main method of purchasing PSP games after Sony shut down access to the store from the PSP on March 31, 2016. Hardware shipments of the PSP ended worldwide in 2014; production of UMDs ended when the last Japanese factory producing them closed in late 2016.
