The 1998Tennessee Oilers season was the 39th season overall and 29th with the league and their final season as the Oilers. The team matched their previous season's output of 8–8, marking their third straight season with exactly eight wins. The Oilers failed to qualify for the playoffs for the fifth consecutive year.
The 1998 season was the only year the Oilers would play in Vanderbilt Stadium, an undersized stadium that was used as a temporary stopgap until the team's new permanent stadium could be constructed. The Oilers, who had originally intended to stay in Houston until the stadium was finished, were forced out of Houston due to poor attendance in 1996, and were again forced out of their "Plan B," Liberty Bowl Memorial Stadium in Memphis, after attendance was even worse there in 1997.
