{{Motorsport season | series = IMSA GT Championship | year = 1998 | nextlink = 1999 American Le Mans Series | nextsuffix = [[American Le Mans Series|ALMS]] }}

The '''1998 [[International Motor Sports Association|Professional SportsCar Racing]] Championship season''' was the 28th season of the [[IMSA GT Championship]], the final one of the original IMSA. It consisted of an open-cockpit World Sports Car (WSC) class of [[Le Mans Prototype|prototypes]] and [[Grand Tourer]]-style racing cars divided into GT1, GT2, and GT3 classes. It began March 22, 1998, and ended October 25, 1998, after eight rounds.

The IMSA GT Championship was replaced by the [[American Le Mans Series]] in 1999, which was supported by the [[Automobile Club de l'Ouest]] (ACO). This series, based on the [[24 Hours of Le Mans]], was initially previewed during the 1998 season with the running of the inaugural [[Petit Le Mans]]. [[International Motor Sports Association|Professional SportsCar Racing]] remained as the series organizer.

Of note is the lack of the [[24 Hours of Daytona]] and the [[Six Hours of Watkins Glen]], both of which were acquired by the revived [[SCCA]] [[United States Road Racing Championship]].
