|Division I-A football seasons|
The 1998 NCAA Division I-A football season was the first of the Bowl Championship Series, which saw Tennessee win the national championship, one year after star quarterback Peyton Manning left for the NFL. The Volunteers defeated the Florida State Seminoles 23-16 in the Tostitos Fiesta Bowl in Tempe, Arizona to secure the inaugural BCS National Championship.
The BCS combined elements of the old Bowl Coalition and the Bowl Alliance it replaced. The agreement existed between the Rose, Fiesta, Sugar, and Orange Bowls, the Cotton Bowl Classic diminishing in status since the breakup of the Southwest Conference. Like the Bowl Alliance, a national championship game would rotate between the four bowls, with the top two teams facing each other. These teams were chosen based upon a BCS poll, combining the AP poll, the Coaches poll, and a third computer component. The computer factored in things such as strength of schedule, margin of victory, and quality wins without taking into account time (in other words a loss in October and a loss in November were on equal footing).
However, like the Bowl Coalition, the bowls not hosting the national championship would retain their traditional tie-ins.
The first run of the Bowl Championship Series was not without controversy as Kansas State finished third in the final BCS standings but was not invited to a BCS bowl game. Ohio State (ranked 4th) and two-loss Florida (8th) received the at-large bids instead. Also, Tulane went undefeated but finished 10th in the BCS standings and was not invited to a BCS bowl because of their strength of schedule. The Green Wave would claim their national championship unrecognized by the NCAA following UCF Knights undefeated season in 2017.
The following rule changes were adopted by the NCAA Rules Committee during their 1998 meeting: 
- Defensive players are allowed to recover and advance backward passes. Previously the defense was only allowed to recover but not advance backward passes.
- Illegal touching of a forward pass by an ineligible receiver is a five-yard penalty from the previous spot but no loss-of-down.
- Defensive players may not rough an offensive player in position to receive a backward pass (i.e. trail man on option play).
- Standardized uniform recognition regarding memorializing of deceased or severely ill teammates/coaches.
- Eyeshields must be clear.
Conference and program changes
