The 2011 Copa del Rey Final was the 109th final since its establishment. The match was a traditional 'El Clásico' rivalry between Barcelona and Real Madrid which took place on 20 April 2011 at the Mestalla Stadium, making it the sixth such Copa del Rey final (the last one was played also in Valencia on 5 April 1990), just four days after the two teams played each other in La Liga and seven days before they played each other in the UEFA Champions League first leg semi-final.

Real Madrid lifted the trophy for the 18th time in their history with a 1–0 victory after extra time.

The match was scoreless after 90 minutes but there had been numerous scoring chances on both sides. Cristiano Ronaldo was credited with having three good chances in the first half, the last of which was kept out with a one-handed save by Barcelona goalkeeper José Manuel Pinto. Barcelona did not have a shot on target in the first half, but in the second they dominated possession, with Andrés Iniesta and Pedro both forcing saves from Real Madrid goalkeeper Iker Casillas. The game was won in the first period of extra time by the game's only goal, a header from Cristiano Ronaldo from a cross from Ángel Di María.

The BBC gave credit to Real Madrid manager José Mourinho's defensive tactics for keeping Barcelona scoreless. When Barcelona's Xavi, Andrés Iniesta, Lionel Messi and David Villa got the ball, they were challenged by two Madrid players. There were many fouls in the match, with the referee issuing eight yellow cards. Real Madrid's Ángel Di María was sent off in the 120th minute after receiving his second booking.
