Camlough (/ˈkæm.lɒx/ KAM-lokh; from Irish Camloch, meaning 'crooked lake')[2] is a village west of Newry in County Armagh, Northern Ireland.

South of the village is Camlough Mountain (or Slieve Girkin), part of the Ring of Gullion[3] and is designated an Area of Outstanding Natural Beauty.

At the time of the Plantation of Ulster, 1000 acres of 12 townlands were granted to Henry McShane O'Neill and the village was developed during this period.

Close to the shore of the lake is an approximately one kilometre long tunnel, wide enough to drive an articulated truck into, which was excavated in the 1960s as part of a planned development intended to create a man-made cavern within Camlough Mountain which was to have been used to store and release water to generate electricity.

Whereas the younger rocks of Gullion are associated with igneous activity related to the formation of the present day Atlantic Ocean, the rocks of Camlough Mountain are associated with igneous activity related to the closure of a precursor to the present day Atlantic, the now long disappeared Iapetus Ocean.

In December 1920, approximately 200 IRA volunteers, led by Aiken, attacked Camlough Royal Irish Constabulary barracks.

British troops sent from Newry were ambushed by the IRA who opened fire and threw grenades from a bridge overhead.

The next day, British forces set fire to several homes and businesses in Camlough in reprisal, many of them owned by Aiken's relatives.

On 19 May 1981, five British soldiers were killed in an Irish Republican Army (IRA) landmine attack on the Chancellors Road 3 miles from Camlough.

Local Swimmer and CLWF Chairman Padraig Mallon then went on to complete the English and North Channel in the same year (only 3rd person to ever do so).

There are currently three Craobh Rua players representing Armagh at senior inter-county level, Fiachra Bradley, Micheal Garvey and Ryan Lewis.

A Guinness World Record for the longest open water relay swim was broken by a team of intrepid swimmers at Camlough Lake in South Armagh on Saturday 19 September 2009.

Camlough is classified as a Village by the Northern Ireland Statistics and Research Agency (NISRA) (i.e. with population between 1,000 and 2,499 people).
