1999–2000 NCAA Division I men's basketball season

The 1999–2000 NCAA Division I men's basketball season began on November 11, 1999, with the Coaches vs. Cancer Classic, progressed through the regular season and conference tournaments, and concluded with the 2000 NCAA Division I men's basketball tournament championship game on April 3, 2000, at the RCA Dome in Indianapolis, Indiana.

Season headlines

 * Tom Izzo led Michigan State to its second national championship behind the play of the "Flintstones," a trio of players from Flint, Michigan. Mateen Cleaves, Morris Peterson and Charlie Bell led the Spartans to an 89–76 win over Florida, with Cleaves named Final Four Most Outstanding Player and Peterson also making the All-Tournament team.
 * Cincinnati was 28–2 and had been arguably the best team in the country when Player of the Year Kenyon Martin had a season-ending leg fracture three minutes into their first-round Conference USA tournament game against Saint Louis. The Bearcats lost that game and gave the NCAA Tournament selection committee a difficult decision to make about seeding. Ultimately, the Bearcats were made a #2 seed in the NCAA tournament and lost in the second round to Tulsa.
 * The preseason AP All-American team was named on November 10. Chris Porter of Auburn was the leading vote-getter (53 of 65 votes). The rest of the team included Quentin Richardson of DePaul (46 votes), Mateen Cleaves of Michigan State (44), Scoonie Penn of Ohio State (44) and Terence Morris of Maryland (30).
 * David Webber scored 51 points for on February 24, 2000, against Ball State. The total was the highest single-game point total of the season in regulation (2nd to Eddie House who had 61 in 2OT to tie Kareem Abdul-Jabbar's Pac-10 record). The tally broke Larry Bird's 1977 McGuirk Arena single-game record performance of 45 points.

Rules changes

 * On uniforms, the use of the single-digit numbers "1" and "2" as player numbers is once again permitted. Their use had been prohibited since the 1957–58 season.
