1977 Copa Libertadores finals

The 1977 Copa Libertadores finals was the final two-legged tie to determine the 1977 Copa Libertadores champion. It was contested by Argentine club Boca Juniors and Brazilian club Cruzeiro. The first leg of the tie was played on 6 September at Boca Juniors' home field, La Bombonera, while the second leg was played on 11 September at Cruzeiro's venue, Estadio Mineirão. It was Boca Juniors and Cruzeiro 2nd Copa Libertadores finals.

Boca Juniors won the series after winning the penalty shootout of a tie-breaking playoff 5–4 at Montevideo's Estadio Centenario, therefore winning their first Copa Libertadores after the final lost in 1963 v. Santos.

Rules
The finals were 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 would be crowned the champion. If the two teams tied on points after the second leg, a playoff in a neutral venue would become the next tie-breaker.
