The 1999 Big Ten men's basketball tournament was the second annual postseason men's basketball tournament for the Big Ten Conference and was played from March 4 through March 7, 1999, at the United Center in Chicago, Illinois. The championship was won by Michigan State who defeated Illinois in the championship game.[1] As a result, Michigan State received the Big Ten's automatic bid to the NCAA tournament.
Due to Michigan basketball scandal, Michigan has vacated the records from this tournament.[2] Similarly, due to the Minnesota academic scandal, Minnesota's appearance in this tournament was vacated.[3] Ohio State also vacated its appearance in the tournament due to NCAA Sanctions.[4]
All Big Ten schools participated in the tournament. Teams were seeded by conference record, with a tiebreaker system used to seed teams with identical conference records. Seeding for the tournament was determined at the close of the regular conference season. The top five teams received a first round bye.
