Greysteel or Gresteel is a village in County Londonderry, Northern Ireland. It lies 9 miles (14 km) to the east of Derry and 7 miles (11 km) to the west of Limavady on the main A2 coast road between Limavady and Derry, overlooking Lough Foyle. It is designated as a Large Village and in the 2001 Census it had a population of 1,229 people, an increase of almost 20% compared to 1991. It is situated within Causeway Coast and Glens district.

The village lies mostly within the townlands of Gresteel More and Gresteel Beg. The name "Greysteel" may be a part-translation of the Irish Glas-stiall, meaning "grey strip (of land)", and the Placenames Database of Ireland gives this as the Irish name of the village. An older English name for the area was "Glasteele".

• On 14 November 1976, Jim Loughrey was shot dead by loyalists at his home.
