This is the 2015-16 Superior International Junior Hockey League season. This was the league's 15th season.
- The plans to add a Kenora franchise were delayed at least one season as potential owners could not secure ice time for the 2015-16 season. The Superior International Junior Hockey League has explored communities in Minnesota, Wisconsin, Northwestern Ontario and possibly Northern Michigan in an effort to expand their league members.
- On January 22, 2016 the SIJHL announced the addition of a conditional expansion team for the 2016-17 season to be based out of the Ralph Engelstad Arena in Thief River Falls, Minnesota. The team had already been approved by USA Hockey and was awaiting approval of Hockey Canada.

The Dryden Ice Dogs were forced to forfeit a February 5th game against the Thunder Bay North Stars due to the use of an ineligible player. Dryden won the game 5-4 in a shootout but the team had used two midget aged affilate players in the game. Hockey Canada development rules allow for only one underage player to dress and compete in a junior A game. Dryden forfeits the 2 points and Thunder Bay is credited with a 1-0 win. All stats from the game will count however. The SIJHL stated Dryden cooperated in the investigation and deemed the offence to be inadvertent with no further action being taken.
