2019-20 Big Ten season

This is the 2019-20 Big Ten Conference men's ice hockey season. This is the conference's 7th season.

 * None

Format
Due to the poor attendance of the neutral site tournaments, and the addition of Notre Dame as a Big Ten team in hockey, the 2019 tournament introduced a new three-week playoff format. In the first round, the No. 1 team in the regular season conference standings receives a bye, and the remaining six play in a set of best-of-three series. The winners of these three playoff series, along with the No. 1 team, will then participate in two semifinal games. Their winners will advance to the Big Ten championship game. .  The tournament champion advances to the 2020 NCAA Division I Men's Ice Hockey Tournament.

All games will be held at the home arena of the highest seed in each match-up, rather than a neutral site. Unlike other playoff-style conference tournaments in college hockey, the Big Ten will only use single-game semifinals and finals to reduce the likelihood of conflicts with other events that may be scheduled at team arenas.

Cancellation of Tournament
The conference announced it would be cancelling its tournament on March 12th due to the COVID-19 global pandemic.
