Hook Head (Irish: Rinn Duáin) is a headland in County Wexford, Ireland located on the east side of the estuary of the three sisters rivers (the Nore, Suir and the Barrow). It is part of the Hook peninsula and is adjacent to the historic townland of Loftus Hall. It is situated on the R734, 50 km (31 mi) from Wexford town. Hook Head is said to have found its way into common English usage in the saying “By Hook or by Crook.” It is claimed that the phrase is derived from a vow to take Waterford by Hook (on the Wexford side of Waterford Estuary) or by Crook (a village on the Waterford side) made by Oliver Cromwell.
