Kogarah Bay is a suburb in southern Sydney, in the state of New South Wales, Australia. Kogarah Bay is located 16 kilometres south of the Sydney central business district and is part of the St George area. Kogarah Bay is in the local government area of the Municipality of Kogarah.
Kogarah Bay takes its name from the small bay on the northern shore of the Georges River. The suburb is surrounded by the suburbs of Carss Park, Blakehurst, Carlton, Beverley Park and Sans Souci. A small group of shops is located on the intersection of Park Road and the Princes Highway.
Kogarah is from an aboriginal word meaning rushes or place of reeds. It had also been written as 'coggera' or 'cogerah' but the current spelling was settled when the railway line came through the area in the 1880s. Kogarah Bay and Beverley Park were originally part of the suburb of Kogarah.
