The CollegeInsider.com Postseason Tournament (CIT) is an American men's college basketball postseason tournament founded by CollegeInsider.com. The tournament is oriented toward teams that did not get selected for the NCAA Division I men's basketball tournament or National Invitation Tournament (NIT) that reside outside of the "major conferences" (defined by CollegeInsider.com as the Power Five conferences, Atlantic 10 Conference, American Athletic Conference, Big East Conference, Conference USA and Mountain West Conference).

The tournament was first contested in 2009. In 2012, it expanded to 32 participating teams, but contracted to 26 teams for the 2016, 2017, and 2019 editions, and 20 teams in 2018. The tournament was canceled in 2020 and 2021 due to the COVID-19 pandemic. In 2022, the tournament was re-launched and rebranded as The Basketball Classic. While neither The Basketball Classic nor the CIT were contested in 2023, CollegeInsider.com announced in early March that the CIT will be revived in a 16-team pod-based format for the 2023–24 postseason. Ultimately, only nine teams agreed to play in the 2024 edition.
