Southwark St Olave was an ancient civil and ecclesiastical parish on the south bank of the River Thames, covering the area around where Shard London Bridge now stands in the modern London Borough of Southwark. The boundaries varied over time but in general the parish stretched east from London Bridge past Tower Bridge to St Saviour's Dock. Southwark St Olave and St Thomas replaced the civil parish in 1896. It was abolished in 1904 and absorbed by Bermondsey parish.
