Eglinton (formerly known as Muff) is a village in County Londonderry, Northern Ireland. It lies east-north-east of Derry, to which it serves as a sleeper village, and west-south-west of Limavady. Eglinton had a population of 3,165 people in the 2001 Census. The City of Derry Airport, also known as Eglinton Aerodrome and formerly as Londonderry Eglinton Airport, lies a short distance from the village.
Eglinton still has an elegant church, former market house, trees around a green and four oaks which started life in Windsor Great Park. The River Muff flows through the village with the afforested Muff Glen being situated just south of the village. At an embankment of Lough Foyle, birdwatchers can find the feeding ground of many seabirds and waders on the mud flats at low tide.
