The 1998 Major League Soccer season was the third season of Major League Soccer. It was also the 86th season of FIFA-sanctioned soccer in the United States, and the 20th with a national first-division league.
The Chicago Fire and Miami Fusion played their inaugural seasons as the league's first two expansion teams.
The NY/NJ MetroStars dropped the New York/New Jersey from their name and rebranded as just MetroStars, with no city, state or regional name attached to it.
The regular season began on March 15, and concluded on September 27. The MLS Cup Playoffs began on September 30, and concluded with MLS Cup on October 25. Chicago became the first expansion team to win MLS Cup and the first to win it in its inaugural season.
