UEP Systems (ウエップシステム) was a Japanese video game developer founded in 1985.

They were best known for their PlayStation-era snowboarding games, though they also released titles for PlayStation 2, Dreamcast, Neo Geo Pocket, and arcade.

The studio's biggest creative release was the quirky 3D action/adventure title Rising Zan: The Samurai Gunman, the studio's only non-sports game, which received sub-par reviews but gained a small amount of cult appeal among gamers at the time.

Despite the success of their early snowboarding titles, UEP struggled financially in the years that followed with a series of commercially unsuccessful games.

After the release of Cool Boarders: Code Alien - another poor seller - for the PlayStation 2 in 2000, the studio disbanded in 2001.
