John Twiggs Myers (January 29, 1871 – April 17, 1952) was a United States Marine Corps general who was most famous for his service as the American Legation Guard in Peking during the Boxer Rebellion. He graduated from the United States Naval Academy in 1892 and was appointed an assistant engineer two years later. In March 1895 he was commissioned a second lieutenant in the United States Marines Corps. The city of Fort Myers, Florida was originally named after J.T. Myers' father.

While not actually portrayed on film, Myers has inspired characters in several films. In the historical epic 55 Days at Peking, Charlton Heston portrayed Marine Major Matt Lewis, commanding the American Legation Guard in Peking during the Boxer Rebellion. In The Wind and the Lion, the fictional Captain Jerome (played by Steve Kanaly) took on Myers' historical role, commanding the Marines dispatched to Tangier during the Perdicaris incident.
