The 2021 College Basketball Invitational (CBI) was a single-elimination men's college basketball tournament consisting of eight National Collegiate Athletic Association (NCAA) Division I teams that did not participate in the 2021 NCAA Division I men's basketball tournament or the NIT.
This event marked the 13th year the tournament has been held, after the 2020 edition was cancelled due to the COVID-19 pandemic.
In February 2021, the CBI was reported to be exploring holding its annual postseason tournament in a neutral site format rather than on campus.

The 2021 bracket was unveiled on March 15.
