PSX (ピーエスエックス, Pīesuekkusu?) is the name of a Sony media center, digital video recorder, and DVD recorder based on the PlayStation 2 video game console. Since it was designed to be a general-function audiovisual device, it was marketed by the main Sony Corporation (whereas Sony Computer Entertainment markets the corporation's specific game-related hardware). It was released in Japan on December 13, 2003. There were plans to release it in other territories in 2004, but in 2005 these plans were postponed indefinitely due to low sales.

The PSX features either a 160 GB or 250 GB hard drive to record television shows, home movies, digital photos, or to play PlayStation 2 and PlayStation titles. The PSX can be linked with the portable PSP device to transfer videos and music. There is also the indication that the PSX will be linked with the PlayStation 3, meaning that existing PSX owners will not be left out. This could possibly mean that the base version of the PS3 would connect to the PSX to form the “home server” version of the PS3.

The PSX is also known for its introduction of Sony's XrossMediaBar (XM interface.
