The cathedral is used by London South Bank University for its annual honorary degree ceremony, by Regent's College for its graduation ceremonies, and by King's College London for its medical and dental degree ceremonies, an association stemming from its merger with Guy's and St Thomas' teaching hospitals, St Thomas' having started as an infirmary attached to the Priory of St Mary.
The cathedral also hosts the London Nautical School's annual Christmas Carol Service.

There are two other cathedrals in Southwark: the Roman Catholic St George's Cathedral Southwark and the Greek Orthodox St Mary's at Camberwell New Road.

Southwark Cathedral is also known for being the home to Doorkins Magnificat, a grey female cat who began visiting the cathedral in 2008 as a stray looking for food and shelter.
 She has since made the Cathedral her permanent home and is often found curled up beneath a radiator or prowling the aisles.
 She became known as a local celebrity and has met both the Mayor of London and Her Majesty Queen Elizabeth II on formal visits to the cathedral.
 Doorkins features in the specially-written children's book ‘Doorkins The Cathedral Cat’ which can be bought from the cathedral shop, and in 2018 was immortalised with her very own stone gargoyle which is positioned inside the cathedral.
