Derry More (from Irish Doire Mór meaning – The Big Oakwood) is a townland in the civil parish of Templeport, County Cavan, Ireland. It lies in the Roman Catholic parish of Corlough and barony of Tullyhaw.

Derry More is bounded on the north by Derry Beg townland, on the west by Derryconnessy and Derrynaslieve townlands and on the east by Moneynure, Prospect, Corlough and Scrabby, Corlough townlands. Its chief geographical features are Brackley Lough, a stream and dug wells. Derry More is traversed by minor public roads and rural lanes. The townland covers 125 statute acres.

In earlier times the townland was probably uninhabited as it consists mainly of bog and poor clay soils. It was not seized by the English during the Plantation of Ulster in 1610 or in the Cromwellian Settlement of the 1660s so some dispossessed Irish families moved there and began to clear and farm the land.

A map of the townland drawn in 1813 is in the National Archives of Ireland, Beresford Estate Maps, depicts the townland as Derrymore.
