Lakefield 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.

Lakefield is bounded on the north by Newtown, Templeport townland, on the south by Mullaghmore, Templeport townland and on the east by Kilsob townland. Its chief geographical features are Lakefield Lough, a sand pit and dug wells. Lakefield is traversed by minor roads and rural lanes. The townland covers 87 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. Lakefield was located in the ballybetagh of Bally Gortnekargie (Irish "Gort na Carraige", meaning 'The Field of the Rock').

The 1609 Ulster Plantation Baronial Map depicts the townland as part of Gortnacargie (now the modern townland of Gortnacargy in Corlough parish).

The 1652 Commonwealth Survey spells the name as Doone.

The 1665 Down Survey map depicts it as Downe.

In the Plantation of Ulster by grant dated 27 February 1610, King James VI and I granted the lands of Gortnekargie containing 4 polls, Dowrie containing 1 poll and Corneha containing 1 poll comprising a total of 300 acres at an annual rent of £3-4s., to John O’Reily and Connor O’Reily, gentlemen. By a deed dated 10 May 1611 between the said Connor McCahir O’Relly of Cargeagh-Callne in County Cavan, gent and John O’Relly of Gortingarge, County Cavan, gent by which they divide between them the 6 poules of land gotten at the last Plantation of the county, viz, the poules of Gortinesimonie, Tirenavan, Dinrewelle, Dune, Dongary and Cornahagh, of which Connor obtained the three first; who is to pay John 10 shillings English yearly in satisfaction of a gallon of land. An Inquisition held at Cavan Town on 31 March 1626 found that the said Cornelius O’Rely, recently of Gortincarge, County Cavan deceased, was seized of said townland of Gortincarge containing 4 polls of land, namely Gortinshemore, Downe and Tyrenewonagh and 2 polls of land in Downe and Corneha. He died on 3 November 1625. His daughter and heir Mor O’Rely was then 15 years old and married. John O’Reily and Connor O’Reily seem to be the great-great grandsons of the chief of the O'Reilly clan, Eamón mac Maolmórdha O’Reilly of Kilnacrott, who ruled East Breifne from October 1596 – 1601. Their genealogy is Conchobhar & Seaán sons of Cathaoir Óg son of Aodh son of Cathaoir son of Eamón of Kilnacrott son of Maolmórdha son of Seaán son of Cathal.
