The 2012–13 Maritime Junior Hockey League season was the 46th season in league history. The season consisted of 52 games played by each MHL team. Upon completion of the regular season, the top qualifying teams will play down for the Kent Cup, the league's playoff championship trophy. The Kent Cup champion will then meet the top teams of the Quebec Junior AAA Hockey League and Central Canada Hockey League in a host city to determine the Eastern Canadian Fred Page Cup champion. The Summerside Western Capitals won the 2013 Kent Cup by losing only 1 game throughout the entire MHL playoffs.
