Old St. Paul's is an historic church of the Scottish Episcopal Church in the heart of Edinburgh's Old Town in Scotland. It stands on the site of the original home of the separate Scottish Episcopal Church, part of the Anglican Communion, which evolved with the adoption of the Presbyterian governance by the established Church of Scotland.

The present building was designed by Hay and Henderson in the Early English style at a cost of £3500, and was completed in 1883. Hay had been a pupil of Sir George Gilbert Scott (architect of Saint Mary's Episcopal Cathedral in the West End of Edinburgh). Two subsequent nave extensions have trebled the building's original length, and the chancel floor has been raised and laid with marble.

The High Altar is made of carved oak in neo-Norman style with grape vine decoration, surmounted with a slab of porphyry. Seven lamps represent the gifts of the Holy Spirit. The Reredos is in gilded oak, and was designed by Hay & Henderson in 1896. The lancet window depicts the crucifixion, with St. Paul and St. Columba on either side. The roof of the nave is a hammer beam structure with wooden gargoyles. The pulpit is made of carved oak, with figures of Saints, and was built in 1892.
