Ballykeel (from Irish An Baile Caol, meaning "the narrow townland/farmstead") is a housing estate off the Crebilly Road in South-East Ballymena, County Antrim, in Northern Ireland.
Ballykeel is divided into two separate estates, with the estate on the Western side known as "Ballykeel 1", built in 1962 to relieve overcrowding in Ballymena, and also to facilitate people coming into the town from the country to work in the factories in Ballymena. "Ballykeel 2" on the Eastern side, was built in 1972, due to further demand for housing. Ballykeel 1 comprises mainly rows of terraced houses parallel to the street, as well as 2 or 3 storey blocks of flats or maisonettes. Ballykeel 2 is built in the Radburn layout, with many of the terraced houses not facing the street, but onto a pedestrian path. Larger houses near the entrance of Ballykeel 2 show where the factory managers once lived and the terraces where the workers lived. There are also some 2-storey blocks of flats in Ballykeel 2.
Due to the closure of many mills and factories, many workers were left unemployed, and by the 1990s, many homes were empty and boarded up. In 2002 The Housing Executive demolished many houses in Ballykeel 2, leaving large green spaces behind. A derelict block of flats was turned into a community centre. Even so, unemployment, drug abuse, and alcohol abuse are still problems on the estate.
