The Church of St John the Evangelist is in the Scottish town of Cumnock, Ayrshire. Designed by William Burges for the 3rd Marquess of Bute, it was constructed between 1878 and 1880.
The church is constructed in the Early Decorated style and follows the plan of Burges's Church of All Saints, Murston in Kent. The nave is of four bays and ends in an unfinished tower.
The church has some significance as the first ecclesiastical building in Scotland to be lit by electricity.[1] The Scottish composer James MacMillan played the organ at the church as a young man.[1]
