The 2014 Copa Sudamericana finals were the final matches of the 2014 Copa Sudamericana, South America's secondary club football competition. The two-legged event was contested between Atlético Nacional of Colombia and River Plate of Argentina. The first leg was played at the Estadio Atanasio Girardot, Medellín, on 3 December 2014 and the second leg was played on 10 December 2014 at the Estadio Monumental, Buenos Aires. Both teams were appearing in their second final.
As a team of the Argentine Zone, River Plate received a bye in the first round, which meant that Atlético Nacional played two matches more to reach the final. River Plate's first two rounds resulted in comfortable victories, with their later matches being more closely contested. In turn, all of Atlético Nacional's were hard fought contests, winning only a round by more than one goal.
A crowd of 44,412 observed the first leg at the Estadio Atanasio Girardot, in which Atlético Nacional opened the scoring following a Orlando Berrío goal. However, a long-range shot from Leonardo Pisculichi in the second half levelled the match at 1–1, which remained the score. Watched by a crowd of 62,000 at the Estadio Monumental, River Plate took an early lead in the second half when Gabriel Mercado scored. Four minutes later, Germán Pezzella extended their lead. River Plate held on to the 3–1 aggregate, winning the tie and securing their first Copa Sudamericana title.
