Cromkill (from Irish Crom Choill, meaning 'the sloping wood'^[1][2]) is a townland in County Antrim, just south of Ballymena.^[3] It borders Ballee to the north, Slaght to the west and Ballycowan to the east.^[4]

The townland first appears in a taxation letter of 1605 under the name 'Ballycronekill', with the form 'Cromkill' first appearing in 1669. The oldest surviving buildings in the townland are a collection of houses on the Cockhill Road, which date from circa 1830.^[5] Cromkill is recorded in the 1911 census of Ireland as having 294 residents, mostly Presbyterian.^[5]
