HMCS Haida is a Tribal-class destroyer that served in the Royal Canadian Navy from 1943 to 1963, participating in World War II and the Korean War. She was named for the Haida people.
The only surviving Tribal-class destroyer out of 27 vessels constructed for the RCN, the Royal Navy, and the Royal Australian Navy between 1937 and 1945, Haida sank more enemy surface tonnage than any other Canadian warship and as such is commonly referred to as the "Fightingest Ship in the Royal Canadian Navy".
Designated a National Historic Site of Canada in 1984, she now serves as a museum ship berthed next to HMCS Star, an active Royal Canadian Naval Reserve Division, in Hamilton, Ontario. In 2018, Haida was designated the ceremonial flagship of the RCN.
