Mechanical Resonance is the debut studio album by the American hard rock band Tesla. It was released on December 8, 1986, by Geffen Records.

Tesla is an American rock band from Sacramento, California. In late 1981, bassist Brian Wheat and guitarist Frank Hannon formed a band named City Kidd, which evolved into Tesla. By 1984, vocalist Jeff Keith, guitarist Tommy Skeoch, and drummer Troy Luccketta had joined the band, forming their classic lineup that appeared on all of the albums and live shows during their initial run. The band adopted the Tesla moniker shortly before recording their first album, as another band with a name similar to City Kidd already existed.
