Sybil Campbell OBE (9 October 1889 – 29 August 1977) was the first woman to be appointed as a stipendiary magistrate in Britain when she became metropolitan police magistrate at Tower Bridge Magistrate's Court in 1945. She was thus the first woman to be a professional magistrate or judge in Britain, and remained the only full-time woman magistrate or judge in England until her retirement in 1961 and the appointment of Elizabeth Lane as a county court judge in 1962.
