Electrical overstress protection of microelectromechanical systems (MEMS) are disclosed herein. In certain embodiments, a MEMS radio frequency system includes a MEMS device electrically connected along a radio frequency signal path that handles a radio frequency signal, and an electrical overstress protection circuit in shunt with the radio frequency signal path and operable to protect the MEMS device from an electrical overstress event, such as an electrostatic discharge (ESD) event received on the radio frequency signal path. The electrical overstress protection circuit includes a metal conductor configured to resonate about at a fundamental frequency of the radio frequency signal.
