Ah, the 90s. The final decade of the millennium started with a bit of everything: conference changes, teams moving up, teams moving to new conferences, and teams dropping football.
1990 FCS Over FBS Victories (9)

- Montana @ Oregon State, 22-15
- Eastern Michigan @ Youngstown State, 24-14

- The Citadel @ South Carolina, 38-35

There was one tie between I-A and I-AA teams in 1990:
- Arkansas State @ Memphis, 24-24
Georgia Southern (12-3 Overall as I-AA Independent) opened the new decade the way the ended the previous one: I-AA champions for the fourth time. They defeated Nevada (13-2 Overall, 7-1 Big Sky Conference) 36-13 on their home field.
The Colonial League changed its name to the Patriot League, which remains the same name to this day. No other conference changes occurred in 1990.
Central Florida joined I-AA independent status from Division II. Meanwhile, Davidson dropped from I-AA Independent to Division III independent status. Fordham moved from I-AA Independent to the Patriot League. Lamar, previously in the Southland Conference, dropped their football program after the 1989 season.
The NCAA handbook has Southeast Missouri State listed as I-AA starting with the 1990 season, however, the school has a starting date of 1991. Ultimately, this makes no difference to the list of I-AA/FCS wins, nor the FCS versus FBS games as SEMO did not have any games against I-A competition in 1990. It must be noted that SEMO did play a full MIAA schedule in 1990, which led us to not include them as I-AA for the 1990 season.
For the fifth season running, the playoff format remained unchanged. A 16 team field was selected with the top four teams seeded and campus sites used through the semifinal round. The championship game was played on December 15 at Paulson Stadium in Statesboro, Georgia for the second straight season.
