Maxis is an American company founded as an independent video game developer in 1987. It is currently a subsidiary of Electronic Arts (EA), and serves as one of the four major labels of the company. Maxis is the creator of one of the best-selling computer games of all time, The Sims and its first sequel, The Sims 2. These titles and their related products are the brand's most popular and successful lines.

Most Maxis titles are simulation-based, though none are considered traditional simulations. Maxis founder Will Wright likens them to "digital dollhouses." Maxis has also released games developed by other production houses, such as A-Train and SimTower.

Maxis was founded in 1987 by Will Wright and Jeff Braun to help publish SimCity on home computers. Before then, the game was only available on a limited basis on the Commodore 64 due to few publishers showing any interest in porting it. The reason for this is because SimCity wasn't a traditional game that had definite "win" and "lose" conditions. The title went on to become, statistically, one of the most popular and successful video games of all time. The SimCity series has spawned multiple sequels and spinoffs. Following the broad success of SimCity 2000, Maxis moved from Orinda, California, to Walnut Creek in 1994.
