Chicago Fire FC has claimed 1 MLS Cup (1998), establishing the club as one of the most successful franchises in league history.
In MLS, championships are determined through the MLS Cup Playoffs, a postseason tournament held after the regular season. The Supporters' Shield is awarded to the team with the best regular-season record, while the MLS Cup goes to the playoff champion. Both trophies are highly coveted, and Chicago Fire has been a consistent contender for both.
