Arderry (from Irish Ard Doire meaning 'The high 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.

Arderry is bounded on the north by Moneynure townland, on the west by Derryconnessy and Muineal townlands, on the south by Teeboy townland and on the east by Tirnawannagh townland. Its chief geographical features are Bunerky Lough (Irish = Loch Bun Adhairc = The Lake of the Butt of the Horn), small streams, dug wells and spring wells.

Arderry is traversed by minor roads and rural lanes.

The townland covers 209 statute acres.

In medieval times the McGovern barony of Tullyhaw was divided into economic taxation areas called ballibetoes, from the Irish Baile Biataigh (Anglicized as 'Ballybetagh'), meaning 'A Provisioner's Town or Settlement'. The original purpose was to enable the farmer, who controlled the baile, to provide hospitality for those who needed it, such as poor people and travellers. The ballybetagh was further divided into townlands farmed by individual families who paid a tribute or tax to the head of the ballybetagh, who in turn paid a similar tribute to the clan chief. The steward of the ballybetagh would have been the secular equivalent of the erenagh in charge of church lands. There were seven ballibetoes in the parish of Templeport. Arderry was located in the ballybetagh of Ballymackgonghan (Irish = Baile Mac Eochagain, meaning 'McEoghan's Town').

In the Plantation of Ulster by grant dated 24 February 1614, King James VI and I granted, inter alia, one pole of Tardirry to Phelim McHugh O'Reyly, Bryan McHugh O'Reyly and Cahir McHugh O'Reyly, the sons of Hugh Reyly, late of Ballaghaneo, County Cavan. Ballaghaneo is now the townland of Ballaghanea in Lurgan Parish, County Cavan, on the shores of Lough Ramor, so the O'Reillys were removed a long way from their home by the Plantation. Hugh Reyly was the great-grandnephew of the chief of the O'Reilly clan, Eoghan na Fésóige mac Seoain, who ruled from 1418–1449. The O’Reilly lands in Arderry were confiscated in the Cromwellian Act for the Settlement of Ireland 1652 and were distributed as follows-
