St Athan (Welsh: Sain Tathan) is a village and community in the Vale of Glamorgan in South Wales. The village and its parish church are dedicated to Saint Tathan. The church dates to the 13th–14th century, though an earlier church was dated to the Norman period. The village and the adjacent dormitory village of Eglwys Brewis are known primarily for the MOD St Athan RAF base. There are two pubs in the village, as well as a football team and the RAF St Athan Golf Club.
