The village lies within the East Londonderry constituency and is represented by Democratic Unionist Party (DUP) member, Gregory Campbell.
The village was originally laid out as a Plantation settlement. The development of the nearby World War II airfield greatly enhanced the size and significance of the village.
RAF Ballykelly opened in 1941 as an airfield RAF Coastal Command and closed in 1971, because of the British Government's defence cuts. The station was transferred to the British Army, who renamed it Shackleton Barracks. The Army was due to leave Shackleton Barracks in early 2008. During World War II an RAF bomber aeroplane on a training run clipped a telephone line behind a church in Ballykelly and crashed, claiming the lives of the crew. The aircraft was carrying out a trials mission involving low level parachuting, but a parachute became entangled with the tailplane, putting the aircraft out of control.
During the Northern Irish Troubles the Droppin Well bombing occurred in Ballykelly, killing 17 people in a local disco and bar. Although one of the most fatal single incidents of the conflict, it was the only fatal Troubles-related incident to take place in Ballykelly.
