St Thomas the Apostle was a parish church in Knightrider Street in the City of London.
In existence by the late twelfth century.
St Thomas’ was, with the majority of the churches in the City, destroyed by the Great fire in 1666., Following the fire, a Rebuilding Act was passed and a committee set up under Sir Christopher Wren to decide which would be rebuilt. Fifty-one were chosen, but St Thomas the Apostle was not among them. Instead the parish was united with that of St Mary Aldermary. Part of the site was used for the creation of Queen Street, though a small portion of the churchyard survived.
