The Prince of Wales Arena was an indoor arena located in Fort William, Ontario. The arena opened in 1919. The arena was located on the same site of the former Fort William Arena which opened in 1905 and burned down in 1912 and the Fort William outdoor rink which was used from 1913 until 1918. The arena was turned over to the Canadian Government and was converted into the Fort William Armouries in 1943. It is unclear if the Armouries facility was used for hockey between 1943 and the opening of the Fort William Gardens in 1951.
