Killearn (Scottish Gaelic: Cill Earnain, meaning "Church of Ernan") is a small village of approximately 1700 people in the Stirling council area of Scotland. The village name stems from the Gaelic Cill Earnain, meaning Ernan's Church; the Ernan in question presumably being one of the canonised individuals of that name who were both relatives and followers of St Columba. (Churches elsewhere in Scotland and Ireland are also dedicated to St Ernan, including St Ernan's Kirk, Aridhglas, Isle of Mull).
The village is located approximately 15 miles (24.1 km) north of Glasgow, 7 miles (11.3 km) east of Loch Lomond, and lies on the northwest flank of the Campsie Fells; most predominantly under the shadow of the volcanic plug of Dumgoyne. The Glengoyne whisky distillery, the Loch Lomond and the Trossachs National Park, the West Highland Way long-distance walking route and the Endrick Water (river) are situated close to the village.
The Church of Scotland congregation at Killearn Kirk falls under the Presbytery of Stirling, within the Synod of Forth. Within the Roman Catholic Church, Killearn falls under the Parish of Saint Anthony within the Roman Catholic Archdiocese of Saint Andrews and Edinburgh; although the Catholic community in Killearn is served by St. Anthony's Church in the neighbouring town of Balfron.
Killearn was the birthplace of the historian and humanist scholar George Buchanan, (February 1506 – 28 September 1582). Buchanan belonged to the Monarchomach movement, which advocated of a form of popular sovereignty. Born at The Moss, Killearn, a monument, (Obelisk), at the centre of the village is dedicated to Buchanan.
