Machinima, Inc. was an American multiplatform online entertainment network owned by WarnerMedia. The company was founded in January 2000 by Hugh Hancock and was headquartered in Los Angeles, California.

It originated as a hub for its namesake, machinima, which uses and manipulates video-game technology to create animation, as well as featuring articles on machinima and content about film and technology. The website initially helped to bring attention to machinima as an art form and to encourage productions based on game engines other than those of id Software's first-person shooter computer game series Quake. Over time, the website's focus shifted to general entertainment programming centered around video game culture, comic books and fandom.

In 2016, the company was acquired by Warner Bros. Digital Networks. In turn, Warner Media was acquired by AT&T in 2018. That December, the company would be re-organized into Otter Media and eventually subsumed by its multi-channel network Fullscreen. In January 2019, Machinima abruptly discontinued their YouTube channels, with their videos set to private. In February 2019, Machinima officially ceased operations.
