The 1998 Brisbane Broncos season was the eleventh in the history of Brisbane's National Rugby League premiership team, the Brisbane Broncos. Coached by Wayne Bennett and captained by Allan Langer, they participated in the newly formed National Rugby League's 1998 premiership and posted their three biggest ever wins in rounds 5, 7 and 15 before finishing the regular season as minor premiers. The Broncos then won the 1998 NRL Grand Final, capturing their fourth premiership in seven seasons.

For the 1998 season the Broncos were joined by future Melbourne Storm coach, Craig Bellamy who would work under head coach Wayne Bennett as performance co-ordinator and assistant coach.

As could be expected by their finish to the 1997 season, Brisbane were solid in their first five matches of 1998, snatching five victories. In rounds five and seven, the Broncos won by a margin of 54 points, which was the club's record at the time. This was followed by shock losses to the Sydney City Roosters and Cronulla, but Langer led them to a big win over Canterbury only to see two more club losses. But the Broncos recovered to post huge wins over Penrith and the Western Suburbs Magpies. The Broncos finished the remainder of the regular season undefeated finishing with 10 wins and 1 draw in their last 11 games. The top try-scorer from the NRL season was Brisbane's Darren Smith.

After a week off granted by winning the minor premiership, the Broncos were smothered out of the game by Parramatta 15–10 in their opening finals match. But they lifted and provided some miracle spark against the Melbourne Storm 30-6 a week later, resurrecting their premiership hopes. A huge win over Sydney City 46–18 in the preliminary final installed them at near unbackable odds against Canterbury in the first NRL Grand Final. The Broncos came back from a 12-10 half time deficit to again win consecutive premierships for the second time, and their fourth in seven seasons with a 38-12 Grand Final victory.

The Broncos were also named "Queensland Sport Team of the Year" at the Queensland Sport Awards.

The Broncos' consistent dominance over other teams at this period of time contributed to the National Rugby League's plans to cut the number of teams down to 14 in order to ensure competitiveness and the long-term financial success of the game. Despite the rationalization of the league, the club has continued to dominate in the modern era of the league, winning two more premierships in 2000 and 2006, as well as reaching another two Grand Finals in 2015 and 2023.

The Broncos' 1998 premiership win came in a year in which their Australian Football League neighbours, the Brisbane Lions, won the wooden spoon.
