The 2010–11 OJHL season is the 17th season of the Ontario Junior Hockey League (OJHL) and the first since the league existed as two separate bodies in 2009–10. The thirty-one teams of the North, South, East and West Divisions will play 50-game schedules.

Come February, the top teams of each division will play down for the Frank L. Buckland Trophy, the OJHL championship. The winner of the Buckland Cup will compete in the Central Canadian Junior "A" championship, the Dudley Hewitt Cup. If successful against the winners of the Northern 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 2011 Royal Bank Cup.
