1999–2000 NCAA Division I men's ice hockey rankings

Two human polls made up the 1999–00 NCAA Division I men's ice hockey rankings, the USCHO.com Division I Men's Poll and the USA TODAY/American Hockey Magazine Poll. As the 1999–00 season progressed, rankings were updated weekly. There were a total of 15 voters in the USA Today poll and 40 voters in the USCHO.com poll. Each first place vote in the USA today poll is worth 15 points in the rankings and 10 points in the USCHO.com poll with every subsequent vote worth 1 fewer point.
