Jeff Braun is an American computer game producer and co-founder of the video game developer Maxis.

Braun had successfully published font packs for the Amiga personal computer when he met Will Wright at a pizza party hosted by Chris Doner in 1987. Wright had been unsuccessful in finding a game publisher for his city-building game SimCity. Braun already had a wire frame jet fighter simulation game he hoped to publish, and when he saw SimCity he told Wright that the two games would give them critical mass to start a new games publisher of their own. They named the company Maxis.

Wright had been an employee of Brøderbund when he first developed the concept, so Braun and he had to return there to clear the rights to SimCity. Brøderbund had just set up a new distribution office to counter the Electronic Arts (EA) Affiliated Label program. Brøderbund executives Gary Carlston and Don Daglow saw SimCity, recognized its potential and urged Braun to sign a distribution deal with Brøderbund for the game. Braun wanted the jet fighter game included in the deal, and Brøderbund agreed.
