One human poll made up the 1999 National Association of Intercollegiate Athletics (NAIA) football rankings, sometimes called the NAIA Coaches' Poll or the football ratings.
Once the regular season was complete, the NAIA sponsored a playoff to determine the year's national champion.
It is not known whether a final poll was taken after completion of the 1999 NAIA Football National Championship, won by Northwestern Oklahoma State.
Through the postseason poll of the 1999 season, the teams and the number of times they have held the #1 weekly ranking are shown below.
The number of times a team has been ranked #1 in the postseason poll (the national champion) is shown in parentheses.
