Belmore Mountain (from Irish: Béal Mór, meaning "big mouth") is a hill in the townland of Gortgall, western County Fermanagh, Northern Ireland. With a summit roughly 398 metres (1,306 ft) above sea level, it is the second highest point in Fermanagh, the highest being at Cuilcagh on the Northern Ireland–Republic of Ireland border in the south of the county. The historian John O Donovan (1834) states that the idigenous population called the mountain Bel Mor Muintir Pheodachain . 
Geologically dominated by limestone, outcropping of the sedimentary rock forms extensive sheer cliffs near the summit. Chemical erosion caused by the natural acidity of water has formed a cave system underneath the mountain, accessible at the village of Boho. Faulting has produced the Knockmore escarpment on the western flanks of Belmore. Other small villages and hamlets around the foot of Belmore include Letterbreen and Springfield.
In 1894, archeologist Thomas Plunkett excavated both the Eagle’s Knoll Cairn passage tomb and Moylehid ring cairn in the townland of Moylehid; one of which is situated on an eastern spur of Belmore Mountain overlooking the Erne valley.
The mountain also gives its name to an Irish earldom. Somerset Lowry-Corry, 4th Earl Belmore, served from 1868 to 1872 as the 14th Governor of New South Wales, where several features are named for him: the Belmore River, the suburb of Belmore in Sydney, Belmore Park, also in Sydney and in Goulburn. The name is also associated with Belmore Forest in the Boho area.
