Mullanacre Lower is a townland in the Parish of Tomregan, Barony of Tullyhaw, County Cavan, Ireland.
The townland name is an anglicisation of the Gaelic placename "Mullagh an Acre" which means ‘The acre of the summit’. In the 17th century it formed part of Carrowmore, County Cavan townland.
It is bounded on the north by Mullanacre Upper townland, on the east by Carrowmore, County Cavan townland, on the south by Drumane & Bofealan townlands and on the west by Moher townland. Its chief geographical features are the Crooked River (Ireland) and Slieve Rushen mountain, on whose southern slope it lies, reaching an altitude of over 600 feet (180 m) above sea-level.
The townland is traversed by the R200 road (Ireland), Carrowmore Lane and other minor lanes.
The townland covers 315 statute acres, including 1-acre (4,000 m2) of water.
It formed part of the Manor of Calva which was granted to Walter Talbot in 1610 as part of the Plantation of Ulster.
