Studio Alex was a Japanese video game development firm. It was founded by respected programmer Kazunari Tomi, a former employee of Nihon Falcom whose credits include Sorcerian, Star Trader, and Dinosaur. After leaving Nihon Falcom, he founded Studio Alex, which functioned primarily as a consultant company.

Studio Alex developed the initial three titles of the Lunar series, with Game Arts as co-developer and publisher. In 2003, the company filed a lawsuit against Game Arts over secondary creator copyrights to Lunar: The Silver Star, but were sued in turn for damages in regards to trouble over the Magic School Lunar theatrical animation, and lost. Studio Alex bankrupted thereafter.
