Taughboyne (Irish: Teach Baoithín meaning "house of Baithen")[1] is a civil parish, in County Donegal, Ireland.

Taughboyne is located 8 km (5.0 mi) West-South-West from Derry, on the road to Raphoe; containing, with the village and ancient disfranchised borough of St Johnston, 6335 inhabitants (in 1837).

St. Baithen, son of Brendan, a disciple and kinsman of St Columba, and his successor in the abbey of Hy, founded Tegbaothin in Tyrconnell: he flourished towards the close of the sixth century.

The parish, according to the Ordnance survey, comprises an area of 15,7733⁄4 statute acres, including a large portion of bog: the land is chiefly arable, and of good quality.

The River Foyle, which bounds the parish on the east, is navigable for small boats to St. Johnstown, where a fair is held on 25 Nov..
