The 1999 UEFA Super Cup was a football match played on 27 August 1999 between the 1998–99 UEFA Champions League winners, Manchester United, and Lazio, winners of the 1998–99 UEFA Cup Winners' Cup.
Against the odds, Lazio won the match 1–0, the winning goal coming from Chilean striker Marcelo Salas in the 35th minute. The match was played at the neutral venue of the Stade Louis II in Monaco in front of 14,461 fans.
This was the last Super Cup contested by the winners of the UEFA Cup Winners' Cup, as the tournament was discontinued after the 1998–99 season. Since 2000, it has been contested by the winners of the UEFA Champions League and the winners of the UEFA Cup/UEFA Europa League.
The Stade Louis II in Monaco has been the venue for the UEFA Super Cup since 1998. It was built in 1985, and is also the home of AS Monaco, who play in the French league system.
