Confederation Square is an urban square in Ottawa, Ontario, Canada, and is considered the second most important ceremonial centre in Canada's capital city, after Parliament Hill. Roughly triangular in area, with Canada's National War Memorial at its centre and the Valiants Memorial at its periphery, the square is bounded by Wellington Street to the north and branches of Elgin Street to the east and west.
The square was designated a National Historic Site of Canada in 1984. Confederation Square's importance is due not only to its central location in Ottawa and its status as a rare Canadian example of a City Beautiful-inspired square, but also arises from the landmark buildings that frame the square: the Château Laurier, the Government Conference Centre, the National Arts Centre, the Central Chambers, the Scottish Ontario Chambers, the Central Post Office, the Langevin Block and the East Block. Part of the square crosses over the Rideau Canal, itself a National Historic Site of Canada and a World Heritage Site.
