1997 Supercopa Libertadores

The 1997 Supercopa Libertadores was the tenth and final season of the Supercopa Libertadores, a club football tournament for past Copa Libertadores winners.

Vasco da Gama were admitted to the tournament for the first time in recognition of winning the South American Championship of Champions in 1948. Argentinos Juniors did not take part. River Plate won the competition for the first time, defeating São Paulo 2–1 on aggregate in the final.

For its final season, the format of the first round was changed from a two-legged knockout round to four groups of four teams playing each other twice. As 17 teams were scheduled to take part, a preliminary round was played to eliminate one team.

As through the successive editions of this cup were added new champions from the Copa Libertadores, in 1997 the Conmebol decided that the last teams of each group would descend to reduce the number of teams to disputed it. That year descended Velez Sarsfield, Racing Club and Boca Juniors (all teams from Argentina) and Gremio (Brazil).
