Marvin's Marvelous Mechanical Museum

Marvin's Marvelous Mechanical Museum is an arcade and museum located in Farmington Hills, Michigan. It is devoted to a large collection of coin-operated animatronic dummies, mechanical games, and other curiosities. Exhibits include, for example, the classic Romani Fortune teller machine that used to grace many carnival sideshows. Most of the machines at the museum are still functional and visitors are encouraged to use them. Marvin's is open 365 days a year. It is currently located in a 5,500-square-foot space.

In late 2023, a new development, including a Meijer store, was proposed which would involve tearing down the building occupied by Marvin's. The choice was approved by the Farmington Hills council on 14 February 2024, although the owner has stated that Marvin's will be relocating.
