The Lough is the name given to a suburb of Cork City, the electoral division in which it lies, the body of water that gives the area its name and home to the Roman Catholic parish of the same name. It lies on the south side of Cork City.
The Lough is a shallow, freshwater lake with an average depth of one metre and a total area of 4 hectares.  It is an important wildfowl preserve, particularly for swans, and has been a protected area since 1881. The Lough is also popular for coarse angling and is home to fish species such as carp, eel, tench, rudd and perch.
