Clew Bay (/ˈkluː/; Irish: Cuan Mó) is a large ocean bay on the Atlantic coast of County Mayo, Ireland. It is roughly rectangular and has more than a hundred small islands on its landward side; Ireland's best example of sunken drumlins. The larger Clare Island guards the entrance of the bay.

The bay is overlooked by Croagh Patrick to the south and the Nephin Beg Mountains to the north. From the southwest part of the bay eastwards are the settlements Louisburgh, Lecanvey, Murrisk, and Westport; north of Westport is Newport, and westwards from there lies Mulranny, gateway to Achill.
