The Church of St John the Evangelist is a Scottish Episcopal church in the centre of Edinburgh, Scotland. It is sited at the west end of Princes Street, and is protected as a category A listed building.
It was dedicated as St John's Chapel on Maundy Thursday 1818 with construction having begun in 1816. It was designed by the architect William Burn the previous year, at the remarkable age of only 25.
The congregation had begun in 1792 when Daniel Sandford came to Edinburgh to minister on Church of England lines. In 1797 the Qualified congregation moved to Charlotte Chapel which was re-built on larger lines in 1811. They sold shares to fund a new church, the banker Sir William Forbes being the main figure, while Charlotte Chapel was sold to Baptists.
Edward Bannerman Ramsay went to St John's as curate in 1827. He succeeded Bishop Sandford as minister in 1830, and stayed till his death in 1872, being dean from 1846.
The sanctuary and chancel were built in 1879–82 by John Dick Peddie and Norman Boyd Kinnear. The vestry and Hall in 1915 to 1916 by John Dick Peddie and Forbes Smith.
St John's holds daily services and is unique in that it is the last church in Scotland to hold the weekly service of Matins.
The plaster ceiling vault is derived from that found in the Henry VII Chapel in Westminster Abbey.
Stained glass is largely by Ballantine, but the east window is by William Raphael Eginton.
The morning chapel was furnished by Walker Todd in 1935.
