Waterloo Town Hall, Victorian architecture town hall in Waterloo, New South Wales, Australia.

Waterloo Town Hall is a Victorian architecture building in Waterloo, New South Wales. It displays classical elements including decorative cornices, large archways, and a symmetrical facade at 770 Elizabeth Street.

The building was constructed between 1880 and 1882 and served as the seat of Waterloo Municipal Council until 1948, when the area merged with Sydney. Following this merger, the structure lost its original administrative purpose.

The name Waterloo commemorates the 1815 battle, and a bronze plaque by sculptor Victor Cusack was unveiled at the hall on 26 July 1990 by Valerian Wellesley, 8th Duke of Wellington. The building is the most recognisable symbol of a suburb that once had a fiercely independent local identity. A Social Hall was added to the rear in 1915.

The library occupies the former council chamber and hall at 770 Elizabeth Street, near the corner with Phillip Street. Enter from Elizabeth Street; the 1996 refurbishment by Stephenson and Turner retained most original internal fittings. The air-raid shelter built during World War II remains at the rear of the building.

During World War II, the building housed an air-raid shelter that still survives today. This shelter remains one of the few preserved wartime bunkers of its kind in Sydney.
