The Toronto City Hall, or New City Hall, is the seat of the municipal government of Toronto, Ontario, Canada, and one of the city's most distinctive landmarks. Designed by Viljo Revell and engineered by Hannskarl Bandel, the building opened in 1965. The building is located adjacent to Nathan Phillips Square, a public square at the northwest intersection of Bay Street and Queen Street, that was designed and officially opened alongside Toronto City Hall.

Toronto City Hall replaced the neighbouring Old City Hall, which was occupied by the municipal government since 1899 and continues to house municipal offices and courts. The building also served as the seat for the Metropolitan Toronto regional government from 1965 to 1992.
