The 2017 Vuelta a España was a three-week Grand Tour cycling stage race that took place in Spain between 19 August and 10 September 2017.

[1] The general classification was won by 2017 Tour de France champion Chris Froome from Team Sky, ahead of Vincenzo Nibali of Bahrain–Merida.

[3] Froome became the third rider to win the Tour-Vuelta double after Jacques Anquetil (1963) and Bernard Hinault (1978), and the first to do so since the Vuelta was moved to its current calendar position.

[7] On 27 March 2017, the organiser of the Vuelta, Unipublic, announced the four second-tier UCI Professional Continental teams given wildcard invitations.

[10] The average age of riders in the race was 27.6 years,[13] ranging from the 20-year-old Lennard Kämna (Team Sunweb) to the 40-year-old Svein Tuft (Orica–Scott).

[17] Chris Froome (Team Sky), who arrived at the Vuelta having won his fourth Tour de France the month before, was considered the favourite by most commentators and bookmakers.

In Quintana's absence, bib number one was handed to three-time winner Alberto Contador (Trek–Segafredo), who announced in early August that he would retire from cycling after the race.

[24] 2010 winner Vincenzo Nibali (Bahrain–Merida) was considered to be Froome's closest rival for overall victory, having skipped the Tour de France.

[19] Fabio Aru (Astana), winner of the 2015 edition, started the race as a favourite as well after he performed well to finish fifth overall at the Tour de France.

Potential favourites to make their debut at the Vuelta were Ilnur Zakarin (Team Katusha–Alpecin), who had finished fifth at the Giro d'Italia in May, as well as both Adam and Simon Yates (both Orica–Scott).

Alberto Contador (ESP) The Vuelta a España had three individual classifications, for which jerseys were awarded daily to the leading rider, as well as a team competition.

[31] There was also a special award with a prize of €1,000, the Cima Alberto Fernández, given to first rider (Miguel Ángel López) to reach the summit of the Alto Hoya de la Mora at the finish of stage fifteen.

[27][31][32] The race was the 25th of the 38 events in the UCI World Tour,[33] with riders from the WorldTeams competing for individually and for their teams for points that contributed towards the rankings.

[35][36] On 13 December 2017, it was announced by Team Sky that Chris Froome was found with 2000 ng/ml of Salbutamol in a sample collected on 7 September, after the finish of stage 18.

If the UCI had found this to be a doping violation, he could have lost his Vuelta title and faced a potential ban from competitive cycling.

[37] On 2 July 2018, the UCI, with the cooperation of WADA, ruled that upon review of the submitted evidence that there was no wrongdoing and closed the case, exonerating Froome and allowing his 2017 Vuelta win to stand.
