Hendrefoilan is an area in Swansea, south Wales. The area overlaps the Northwest of Sketty and eastern Killay communities.
The western part is often known as Student Village. The Student Village is on the West bank of the Olchfa stream, so is in fact in Killay. It is part of a Satellite Campus of Swansea University. The student village consists of a number of student flats which are let out to students of Swansea University. Also on the campus is Hendrefoilan House, formerly a large private House, which hosted the South Wales Miners' Library until 2006, and another University building which until 2006 housed the Education Library, but now contains the relocated South Wales Miners' Library. Hendrefoilan house was built in 1857 by Lewis Llewelyn Dillwyn (1814-92) then the member of Parliament for Swansea.
The eastern part is sometimes known as the "Hendrefoilan Estate". It is within the Sketty Community, and part of the Tycoch electoral Polling District, although would not be considered "culturally" part of Tycoch. The area has an SA2 7** postcode, and is hence considered by Royal Mail to be in the Killay/Dunvant area. It is bounded by the Olchfa Stream to the west, the Gower Road to the South, and University Perimeter fence and Hendrefoilan Road to the North. The area consists of suburban housing.
