ELF Corporation (エルフ or élf) is a hentai game studio that got its start in Tokyo on April 27, 1989. The company operated until 2015, with Atsushi Shimoda heading it as CEO from 2004 onward.

Best known for Dōkyūsei, a hugely influential dating sim that basically helped define the genre, ELF built a solid reputation in adult gaming. The game spawned a sequel plus adaptations into video and TV series. Interestingly, the main villain designs from the -saku series became the studio's official mascot—a detail fans often note as pretty typical of the company's quirky brand identity.
