Belturbet (/bɛlˈtɜːrbət/; Irish: Béal Tairbirt, meaning 'mouth of the isthmus')[8] is a town in County Cavan, Ireland.

In the late 16th century the local O'Reilly chieftains built a castle opposite Turbet Island, but this has not survived either.

As part of the Plantation of Ulster in the early 17th century, the lands around Belturbet were granted to the English "undertaker" Stephen Butler.

In March 1653, under Viscount Magennis of Iveagh, it was the last town in Ireland to fall to Cromwell; the final Irish stronghold at nearby Cloughoughter held out for a further month.

John Wesley passed through in 1760, and noted[12] a town in which there is neither Papist nor Presbyterian; but, to supply that defect there are, Sabbath-breakers, drunkards, and common swearers in abundance.Two young people, Geraldine O'Reilly, from Staghall, Belturbet, and Patrick Stanley, from Clara, County Offaly, were killed by a Loyalist car bomb in Belturbet on 28 December 1972.

Leydons Coaches operate route 930 linking the town to Cavan, Ballyconnell, Bawnboy, Swanlinbar and Enniskillen.

[26] Tourism facilities include fishing, boat cruising, the local railway station and country walks.

The Erne Palais Ballroom is one of the buildings in the town listed by the National Inventory of Architectural Heritage.

[28] From 1893 to 1931, Shan Fadh Bullock wrote 14 novels set in the Cavan-Fermanagh borderland, renaming Belturbet "Bunn" for his books.

Irish stamp collectors consider the most important prestigious postal cover sent abroad from Ireland to be one from Belturbet posted to Spain on 27 April 1841.
