St Brendan's Chapel, also known as Kilbrannan Chapel, and Skipness Chapel, is a medieval chapel near Skipness, Argyll and Bute, Scotland. The chapel appears to have been built in the late 13th or early 14th century and was dedicated to St. Brendan. The chapel replaced an earlier chapel dedicated to St. Columba at nearby Skipness Castle. There is reason to suspect that the introduction of St Brendan's cult at Skipness was carried out by the Stewarts, after their acquisition of the Clann Suibhne lordship in the mid thirteenth century. By the fourteenth century, St Brendan was closely associated with the Stewarts and their island of Bute.
