Tullandreen (from Irish Tulaigh an Draighin, meaning 'The Hill of the Blackthorn') 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.

[2] 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.

[3] The Ordnance Survey Name Books for 1836 give the following description of the townland- The townland is bounded on the north and east side by a large stream.
