Broadhaven Bay is a natural bay of the Atlantic Ocean on the northwestern coast of County Mayo, Ireland. The opening of the bay faces northward, stretching 8.6 km between Erris Head in the west and Kid Island/Oileán Mionnán in the east.
It borders the parishes of Kilcommon, Kiltane and Kilmore Erris in the Barony of Erris. Landscape largely consists of Atlantic blanket bog interspersed with some areas of machair and white sandy beaches. Population is relatively low, mainly concentrated around inlets along the coastline.
