Abercorn (Gaelic: Obar Chùirnidh, Old English: Æbbercurnig) is a village and civil parish in West Lothian, Scotland.

William J. Watson proposed that the second element meant 'horned', from a Brittonic word related to Welsh corniog.

[4] The church itself dates partially from the 12th century, although its most interesting features are the private aisles created for the three major families of the area, the Dalyells, the Hamiltons, and later the Hopes, who had their own enclosure behind the altar built by architect William Bruce.

[5] Older burial monuments include Norse "hogback" grave markers, and fragments of 7th-century Northumbrian crosses.

[6] On the approach to the church, the Factor's house is a prominent L-shaped building in the Scottish baronial style, built circa 1855.

In 681, during the reign of King Ecgfrith of Northumbria, Theodore of Tarsus, Archbishop of Canterbury, appointed Trumwine "Bishop of the Picts", with his seat at Abercorn.

[12] Four years later, Trumwine may have been present at the defeat and death of Ecgfrith at the Battle of Dun Nechtain,[13] after which he was forced to flee from his Pictish bishopric, retiring to the monastery at Whitby.
