St Magnus the Martyr, London Bridge is a Church of England church and parish within the City of London. The church, which is located in Lower Thames Street near The Monument to the Great Fire of London, is part of the Diocese of London and under the pastoral care of the Bishop of London and the Bishop of Fulham. It is a Grade I listed building. The rector uses the title "Cardinal Rector", being one of three clerics in the Church of England to use the title Cardinal.

St Magnus lies on the original alignment of London Bridge between the City and Southwark. The ancient parish was united with that of St Margaret, New Fish Street, in 1670 and with that of St Michael, Crooked Lane, in 1831. The three united parishes retained separate vestries and churchwardens. Parish clerks continue to be appointed for each of the three parishes.

St Magnus is the guild church of the Worshipful Company of Fishmongers and the Worshipful Company of Plumbers, and the ward church of the Ward of Bridge and Bridge Without. It is also twinned with the Church of the Resurrection in New York City.
