The 1999 Major League Soccer season was the fourth season of Major League Soccer. It was also the 87th season of FIFA-sanctioned soccer in the United States, and the 21st with a national first-division league. This was the last season which used the 35 yard line shootout rule to resolve tied games, and that of the countdown timer, with MLS Cup 1999 adopting the IFAB-standard running clock thereafter.
The Columbus Crew moved into the first soccer-specific stadium when Columbus Crew Stadium opened on May 15, 1999.
The regular season began on March 20, and concluded on October 10. The 1999 MLS Cup Playoffs began on October 16, and concluded with MLS Cup 1999 on November 21. D.C. United won their second double by winning the Supporters' Shield and defeating the Los Angeles Galaxy in MLS Cup.
