2018 Copa Libertadores finals

The 2018 Copa Libertadores finals, also known as The Greater Final (La Gran Final) was the two-legged final to decide the winners of the 2018 Copa Libertadores, the 59th edition of the Copa Libertadores, South America's premier international club football tournament organised by CONMEBOL. The first leg was hosted by Boca Juniors at the Estadio Alberto J. Armando in Buenos Aires, Argentina, on 11 November 2018, while the second leg took place outside South America at the Santiago Bernabéu Stadium in Madrid, Spain (a neutral venue) on 9 December 2018. This was the last final to take place over two legs, as starting from 2019 the final would be played as a single match at a venue chosen in advance.

The finals were contested in a two-legged home-and-away format between Argentine clubs Boca Juniors and River Plate, making it, as of 2025, the only Superclásico final of an international competition and the only time both Copa Libertadores finalists represented the same country other than Brazil. As of 2025, this is also the last final to not feature a Brazilian team. This final is also the last final not won by a club from Brazil.

The second leg was originally to be hosted by River Plate at the Estadio Monumental Antonio Vespucio Liberti in Buenos Aires, Argentina, on 24 November 2018. However, due to safety concerns arising from an attack on the Boca Juniors team bus prior to the match, the second leg was moved outside of Argentina and South America, later confirmed to be the Santiago Bernabéu Stadium in Madrid, Spain. This was the first, and as of 2025, only time that the second leg of the Copa Libertadores final has been held outside of South America, and the first and only final held outside of the Americas.

River Plate won the final 5–3 on aggregate for their fourth Copa Libertadores title. As winners, they qualified as the CONMEBOL representative at the 2018 FIFA Club World Cup in the United Arab Emirates, entering in the semi-finals. They also earned the right to play against the winners of the 2018 Copa Sudamericana in the 2019 Recopa Sudamericana. River Plate also automatically qualified for the group stage of the 2019 Copa Libertadores.

Due to the intense rivalry between Boca and River, the match was referred to as the "Superfinal", and "the final to end all finals". The press called it the "most important final in Argentina's football history". According to Richard Martin, a Reuters reporter, River's win "guarantees them bragging rights over their neighbours for many years to come".

For the third time, two teams from the same country faced each other in the final, after Brazilian teams met in the 2005 and 2006 finals. It was the first all-Argentine final of the Copa Libertadores, as well as the first final to feature two teams from the same city. The 2018 finals marked the first time that the Superclásico was contested in the Copa Libertadores final (or any final of an international competition), and the third time that the two clubs have met in a final, after the 1976 Nacional championship final and the 2017 Supercopa Argentina.

Their most recent meeting in the Copa Libertadores had been in the 2015 round of 16, where Boca Juniors were disqualified and the tie awarded to River Plate, after River Plate players were attacked in la Bombonera stadium with pepper spray by Boca Juniors fans as they emerged for the second half of the second leg, with River leading on aggregate 1–0.
