The 2017–18 Big Ten men's basketball season began with practices in October 2017, followed by the start of the 2017–18 NCAA Division I men's basketball season in November. The 2018 Big Ten tournament was held at Madison Square Garden in New York. Due to the Big East's use of that venue for the 2018 Big East tournament, the Big Ten tournament took place one week earlier than usual, ending the week before Selection Sunday. As a result, the conference season began on December 1, 2017 and concluded on February 25, 2018. Each team played one road game and one home conference game in the first week of December. With a win over Wisconsin on February 25, 2018, Michigan State clinched the outright Big Ten championship, their eighth under Tom Izzo.
