The Almaguin Spartans are a Canadian Junior ice hockey team based in South River, Ontario, Canada. They play in the Greater Metro Junior A Hockey League. They were originally the Mattawa Voyageurs of Mattawa, Ontario.
The Voyageurs were announced in the spring of 2011.
On September 16, 2011, the Voyageurs played their first ever game, at home, against the Bobcaygeon Bucks. The Voyageurs would end up losing the game in a shootout 5-4, but picked up a point for their regulation tie. On the 18th, at home again, the Voyageurs picked up their first ever win 5-4 in overtime over the Algoma Avalanche.
In March 2015 Myles Pepin was promoted from assistant coach and was named the team's new head coach.
The team would win their first nine games of the 2018 playoffs and then defeated the St. George Ravens in six games to claim the Russell Cup championship.
