The 2020 Vuelta a España was the 75th edition of the Vuelta a España, one of cycling's three grand tours. It was won for the second consecutive year by Primož Roglič of Team Jumbo–Visma.

The Vuelta a España is an annual multi-stage bicycle race primarily held in Spain, while also occasionally making passes through nearby countries. Inspired by the success of the Tour de France and the Giro d'Italia, the race was first organised in 1935. The race was prevented from being run by the Spanish Civil War and World War II in the early years of its existence; however, the race has been held annually since 1955. As the Vuelta gained prestige and popularity the race was lengthened and its reach began to extend all around the globe. Since 1979, the event has been staged and managed by Unipublic, until in 2014, when the Amaury Sport Organisation acquired control. Since then, they have been working together. The peloton expanded from a primarily Spanish participation to include riders from all over the world. The Vuelta is a UCI World Tour event, which means that the teams that compete in the race are mostly UCI WorldTeams, with the exception of the wild card teams that the organizers can invite.
