The 2009 Copa Sudamericana de Clubes (officially the 2009 Copa Nissan Sudamericana de Clubes for sponsorship reasons) is the 8th edition of the CONMEBOL's secondary international club tournament. Internacional were the defending champions, having won the trophy the previous season. Ecuadorian side LDU Quito won the 2009 tournament, becoming the first Ecuadorian winners of the trophy.
From this edition onward, CONCACAF teams, which have participated in the tournament since 2005, will no longer be participating because of the format change in the CONCACAF Champions League, which conflicted with scheduling.[1] This will also mark the last tournament in which Argentine clubs River Plate and Boca Juniors will be invited to participate without qualification. Further changes include the additional allocation of berths (1) to all the countries except Brazil and Argentina.[2]
