The 2009 Copa Libertadores de América was
the 50th edition of the Copa Libertadores,
CONMEBOL's premier annual international club
tournament.

The tournament was won by Argentine club
Estudiantes de La Plata, who achieved their
fourth Copa Libertadores title and first in 39
years. Since the inception of a preliminary
round in 2004, they are the first club to start
in that round and win the Copa Libertadores. Estudiantes earned a berth to play in the 2009
FIFA Club World Cup and 2010 Recopa
Sudamericana.
