The 1998 Arizona Diamondbacks season was the Diamondbacks' inaugural season. They looked to contend in what was a strong National League West. They finished the season 33 games behind the National League Champion San Diego Padres with a record of 65–97, last in the division.
Jeff Suppan was the last player from the inaugural team still active in Major League Baseball when he retired in 2012.
