The 1998 Adelaide Rams season was the Adelaide Rams' second and final season as a rugby league club. They competed in the first season of the National Rugby League. The club was again coached by Rod Reddy and captained by Kerrod Walters. However, after the Rams lost nine of their first ten games, coach Reddy and the entire coaching staff were sacked by the Rams' administration. Reddy was replaced by former Perth Reds coach Dean Lance.
