The 1998 NRL Grand Final was the conclusive and premiership-deciding game of the 1998 NRL season. It was the first grand final of the re-unified National Rugby League and featured minor premiers and the previous year's Super League premiers, the Brisbane Broncos against the Canterbury-Bankstown Bulldogs, who had finished the regular season ninth to make a top-ten play-off grouping. It was to be the first grand final under the National Rugby League partnership's administration and the last to be played at the Sydney Football Stadium. It was also the first time these two sides had met in a grand final.

The Clive Churchill Medal is the award given to the player judged to be man-of-the-match in the National Rugby League's annual Grand Final. The award was created to honour Clive Churchill, one of the greatest rugby league players in Australian history, following his death in 1985. A prestigious honour in the NRL, the medal's recipient is chosen by the selectors of the Australian national team and announced and awarded at the post-grand final ceremony.
