The Hook Peninsula is a peninsula in County Wexford, Ireland. It has been a gateway to south-east Ireland for successive waves of newcomers, including the Vikings, Anglo-Normans and the English.
The coastline has a number of beaches. The peninsula's fishing villages, bird watching on the mudflats of Bannow Estuary, deep sea angling, snorkeling and swimming are part of the area's maritime life. The area's rivers, valleys, estuaries and hills have long provided south-west Wexford with rich grazing land.
