The 2012–13 NOJHL season was the season of the Northern Ontario Junior Hockey League (NOJHL). The seven teams of the NOJHL played 48-game schedules. Come February, the top teams of each division will play down for the Copeland-McNamara Trophy, the NOJHL championship. The winner of the Copeland-McNamara Trophy will compete in the Central Canadian Junior "A" championship, the Dudley Hewitt Cup. If successful against the winners of the Ontario Junior Hockey League and Superior International Junior Hockey League, the champion would then move on to play in the Canadian Junior Hockey League championship, the 2013 Royal Bank Cup.
