Douglas (Irish: Dúglas) is a suburb in Metropolitan Cork that is situated 4 km south of Cork, Ireland. As its borders are ill-defined and it straddles the boundary between Cork City and County Cork, it is difficult to ascertain the exact population. The CSO gives a figure of 18,192 for the parts of Douglas that lie within Cork County. No figure is provided for the parts within Cork City, although the combined population of the Tramore A, Tramore B and Tramore C electoral divisions, which lie in Douglas, is 5,001. The name derives from the Irish words Dubh Ghlas, meaning Dark Stream, which still flows through the village. The stream flows into Cork Harbour.
