Circular Quay is a locality in Sydney, New South Wales, Australia. It is located on the northern edge of the Sydney central business district on Sydney Cove, between Bennelong Point and The Rocks. It is part of the local government area of the City of Sydney. Circular Quay is made up of walkways, pedestrian malls, parks and restaurants. It hosts a number of ferry quays and a train station.

Sydney Cove was the site of the initial landing of the First Fleet in Port Jackson. Circular Quay was originally mainly used for shipping and slowly developed into a transport, leisure and recreational centre. Circular Quay was originally known as "Semi-Circular Quay", this being the actual shape of the quay. The name was shortened for convenience.[2] The Circular Quay railway station was opened on the 20 January 1956 and the elevated Cahill Expressway was opened on the 14 March 1958.

Circular Quay was the focal terminal point of most electric tram services to the eastern suburbs. The first tram to operate through Circular Quay was horse-drawn, running from the old Sydney Railway station to Circular Quay along Pitt Street in 1861[3] allowing easy transfer to ferries. Trams operated from Central station down Castlereagh St to Circular Quay and back up Pitt St in a large anti-clockwise loop. For many years, 27 regular services operated from Circular Quay.
