The Copa Mercosur (Spanish pronunciation: [ˈkopa meɾkoˈsuɾ], Portuguese: Copa Mercosul [ˈkɔpɐ meʁkoˈsuw], "Mercosur Cup") was a football competition played from 1998 to 2001 by the traditional top clubs from Brazil, Argentina, Paraguay, Uruguay and Chile. The competition was created by CONMEBOL to generate TV money to the participating teams, but it went beyond and ended up, together with the Copa Merconorte, as natural replacement to the CONMEBOL Cup. These two, Copa Merconorte and Copa Mercosur, were replaced in 2002 by the Copa Sudamericana.

Twenty teams played in the tournament. The teams were divided in five groups of four teams each and the matches were played in two legs. The group winners and the best three runners-up qualified for the quarterfinals. The quarterfinals, the semifinals were played in two legs. In 1998 and 2000 the finals were played in three legs. In 1999 and 2001 the finals were played in two legs.

Throughout the brief history of the competition a total of five venues were used to host the final series:
