Mamie Stuart (c. 24 November 1893 - November or December 1919) was a 26-year-old English woman who disappeared from her home in Caswell Bay, Wales, in 1919 and whose disappearance became known via the media as the Chorus Girl Mystery. Her husband, George Everard Shotton—who had bigamously married Stuart in 1918—was considered the prime suspect in her disappearance. Although investigators strongly suspected foul play, as no body could be found, Shotton could not be tried for Stuart's murder. He was instead convicted of bigamy and sentenced to eighteen months' imprisonment.
