The Mendon Twin Drive-In is a drive-in theater in Mendon, Massachusetts.

Opened on June 14, 1954, it is currently owned by Dan Andelman and his brothers Dave Andelman and Michael, who purchased the drive-in in March 2014 from Susan Swanson and Kathy Gorman, who had operated it since 1986. ^[1][2] It can accommodate 800 cars. The second screen was added in 1998.^[3] Both screens broadcast movie soundtracks using FM radio signals; there are no remaining metal audio speakers on the poles.

As of 2015, it was one of three remaining drive-Ins in Massachusetts. The Andelmans have added a 5,000-square-foot outdoor patio where they offer beer and wine.^[4]
