Carrowmore Lake (Irish: Loch na Ceathrún Móire)[1] is situated in the parishes of Belmullet, Kiltane and Kilcommon Erris, County Mayo between the villages of Bangor Erris and Barnatra at the southern end of Broadhaven Bay.

Its shorelines are dominated by blanket bog mainly but there are many houses, mainly linear in layout, along both sides of its shores.

[3] Its catchment area includes the townland of Bellanaboy in Kilcommon where the contentious Corrib Gas refinery is situated.

The fort of Rathmorgan on the mountain at the south west corner of the lake is the site of the Táin Bó Flidhais cattle raid on Erris from Cruachan in Tulsk, County Roscommon, a tale from the Iron Age cycle of folklore.
