The 1983 Copa Libertadores de América finals was the final two-legged tie to determine the Copa Libertadores de América champion. It was contested by Brazilian club Grêmio and Uruguayan club Peñarol. The first leg of the tie was played on 22 July at Estadio Centenario in Montevideo, with the second leg played on 28 July at Estádio Olímpico Monumental in Porto Alegre.
With the first game tied 1-1, Grêmio were crowned champions after winning the second leg 2–1.[1]
| Team | Previous finals appearances (bold indicates winners) | |
|---|---|---|
| Peñarol | 7 (1960, 1961, 1962, 1966, 1965, 1970, 1982 | |
| Grêmio | None |
The finals was played over two legs; home and away. The team that accumulated the most points —two for a win, one for a draw, zero for a loss— after the two legs was crowned champion. If the two teams were tied on points after the second leg, a playoff at a neutral was to be the tie-breaker. Goal difference was to be used as a last resort to crown a champion.
