The Denver Invaders were a minor pro ice hockey team that played in Denver, Colorado in the Western Hockey League (minor pro) (WHL) during the 1963-1964 season. They were the Spokane Comets before they moved to Denver. They played their regular season games at the Denver Coliseum, and their playoff games at the arena at the University of Denver. The team moved after the '63-'64 season and became the Victoria Maple Leafs.
The Denver Invaders were the farm club for the Toronto Maple Leafs. The head coach was Rudy Pilous, who had been fired the year before from the head coaching job with the NHL Chicago Black Hawks.
In their one season in Denver coached by Rudy Pilous, the Invaders won the regular season championship with the best record in the Western Hockey League, and as such was awarded the WHL Governor's Trophy. The Invaders would lose to the Los Angeles Blades in the playoffs.
