Crossmakelagher (from Irish: Cros Mhic Chéileachair, meaning 'McKelleher's Crossroad; Locals abbreviate it as 'Cross') is a townland in the civil parish of Templeport, County Cavan, Ireland. It lies in the Roman Catholic parish of Templeport and barony of Tullyhaw.
Crossmakelagher is bounded on the north by Cavanaquill and Killynaff townlands, on the west by Tonyhallagh and Tonyrevan townlands, on the south by Bellaheady and Killarah townlands in Kildallan parish and on the east by Cormeen townland in Kildallan parish and Lecharrownahone townland. Its chief geographical features are the Shannon-Erne Waterway, a small plantation, a pond, a quarry, a spring well and several dug wells. Crossmakelagher is traversed by the regional R205 road, minor roads and rural lanes and the disused Cavan and Leitrim Railway.
The townland covers 197 statute acres.
Up until the 18th century it was divided into two different townlands, the part north of the present R205 main road was Crossmakelagher and the part between the R205 and the Shannon-Erne Waterway was called Drumcon (from Irish: Druim Con, meaning 'The ridge of the Greyhounds'). Crossmakelagher was also called Barne at the time ({Irish derived place name|Bearn, meaning 'A Gap'}).
The 1609 Baronial Map depicts the townland as Cross.
