The Copa Libertadores 1975 was an association football competition contested between the top clubs of the CONMEBOL federation. Defending champions Independiente won the competition, defeating Unión Española 2âÂÂ0 in a play-off after the original two legs finished 2âÂÂ2 on points. This was Independiente's fourth Copa Libertadores title in a row and a record-extending 6th title.
The champions and runners-up of each football association were drawn into the same group along with another football association's participating teams. Three clubs from Argentina competed as Independiente was champion of the 1974 Copa Libertadores. They entered the tournament in the Semifinals.
