A currach (Irish: curach, Irish pronunciation: [ˈkʊɾˠax]) is a type of Irish boat with a wooden frame, over which animal skins or hides were once stretched, though now canvas is more usual. It is sometimes anglicised as "Curragh". The construction and design of the currach are unique to the west coasts of Ireland and Scotland, with variations in size and shape by region. It is referred to as a naomhóg (Irish pronunciation: [nˠəi'βˠo:gˠ]; in counties Cork, Waterford and Kerry and as a "canoe" in West Clare. It is related to the Welsh coracle. The plank-built rowing boat found on the west coast of Connacht is also called a currach or curach adhmaid ("wooden currach"), and is built in a style very similar to its canvas-covered relative.

The currach has traditionally been both a sea boat and a vessel for inland waters.
