Carey Bay is a suburb of the City of Lake Macquarie in New South Wales, Australia, and is located on a peninsula southeast of the town of Toronto on the western side of Lake Macquarie. The spelling "Cary Bay" was gazetted on 31 August 1973, but was gazetted and signed "Carey Bay" on 31 May 1991 when the boundaries were determined. In 2001, the Lake Macquarie City Council voted to use the latter name for the suburb.
