2020–21 NCAA Division I men's basketball rankings

Two human polls made up the 2020–21 NCAA Division I men's basketball rankings, the AP Poll and the Coaches Poll, in addition to various publications' preseason polls.

With the release of the poll on November 30, Kansas was ranked in the AP poll for the 223rd consecutive week, breaking the record set by UCLA from 1966–1980. Nine weeks later, with the release of the poll on February 8, the streak that began with the February 2, 2009 poll would end at 232.
