Mt. Edgecumbe High School was instituted on Japonski Island in Sitka in 1947 on the then-recently deserted Sitka World War II installation.
Sitka High's traditional rivals consist of the boarding school Mt. Edgecumbe High School which is also located in Sitka (across the O'Connell Bridge on Japonski Island), and its 4A southeast rivals Juneau-Douglas High School and Ketchikan High School, however the recent change to 3A means the Juneau-Douglas Bears and the Ketchikan Kings no longer compete against the Sitka Wolves for regional and state titles.
