The town belongs to an ancient tuath called Conmhaícne Dúna-Móir and Cenél Dubáin, ruled by Uí Conchobair of Ui Briuin Ai from the 12th century, and a capital of Connacht for a time. King Tairrdelbach Ua Conchobair died here in 1156.
The ruins of Dunmore Castle are situated on a small hillock outside the village. The first castle at this site was built by the Anglo-Norman de-Birmingham family in the early 13th century. Designed as a bulwark against the native Irish, the castle was attacked in 1249 and burned by the O’Connor's. In 1284 it was besieged by the forces of Fichra O’ Flynn. In 1315 it was once more the scene of conflict when an army, led by Rory Connor, attacked and damaged the fortress.
The local association football (soccer) club, Dunmore Town AFC, was founded in 1979 and fields some underage teams in the Roscommon League.
Dunmore RFC was founded in 1977 and Dunmore Demesne Golf Club in 1998.
