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, ultimately named after St. King Olaf II of Norway.

The boundaries varied over time, but in general the parish stretched east from London Bridge past Tower Bridge to St Saviour's Dock.

Part of its area was split off around 1550 to create Southwark St Thomas, corresponding to the hospital of the Archbishop of Canterbury.

[1] In 1733, part of area was used to create Southwark St John Horsleydown.

In 1900 the combined parish became part of the Metropolitan Borough of Bermondsey and was abolished in 1904, with its former area absorbed into the Bermondsey civil parish, as was that of St John Horsleydown.
