Pedro Delgado Robledo (pronounced [ˈpeðɾo ðelˈɣaðo roˈβleðo]; born 15 April 1960), also known as Perico ([peˈɾiko]), is a Spanish former professional road bicycle racer. He won the 1988 Tour de France, as well as the Vuelta a España in 1985 and 1989. He finished in the top 10 of eighteen Grand Tours.

Delgado tested positive for the known masking agent Probenecid during the 1988 tour. The drug, which had been placed on the International Olympic Committee's list of banned substances in January of that year, had not yet been banned by the sport's governing body, the Union Cycliste Internationale; as a consequence, Delgado was allowed to continue racing and was not charged with any doping offence.

Since 1995, he works as a sports commentator for Televisión Española during important cycling events, first along with journalist Pedro González, and, after his death in January 2000, with Carlos de Andrés.

Delgado took part in the Tour de France eleven times. During his first participation, when he was 23, he rose to second place in the overall classification after the 17th stage, before falling back later in the event.

In 1983, the Reynolds team participated in the Tour for the first time. Delgado was a young rider, and Ángel Arroyo was the star of the team. That year the Tour had four individual time trials (ITT), plus the prologue, and six mountainous stages. After the 17th stage Delgado was second in the overall classification, 1m08s behind Laurent Fignon, another 23-year-old rider competing in the Tour for the first time. However, Delgado drank a spoilt milk shake that caused him a stomach cramp during the next stage, ending in Morzine. He lost 25 minutes 34 seconds that day, and his first chance of winning the Tour. He finished in 15th position, 25 minutes 44 seconds behind Fignon.

Delgado fought a long battle with Stephen Roche during the 1987 Tour de France, that was resolved in favour of Roche only in the penultimate stage, an ITT. The final difference was 40 seconds, at the time the second smallest difference ever recorded. Delgado was regarded as the third best time-trialist that year, with Roche considered the best. Roche later said:

"We were on French TV after the descent into Morzine [the last mountain stage, after which Delgado was still leader of the overall classification] and, off camera, he came up to me, hugged me, and said 'Bravo, you deserve the yellow jersey'. The TV people couldn't believe it! He's a fabulous competitor, but he's also a great, incredibly gallant guy and I think that's another reason why that Tour was so special."

Delgado won the 1988 Tour de France by a comfortable margin. The evening after the 17th stage, the television channel "Antenne2" reported that Delgado had tested positive in a doping test. His team director José Miguel Echevarri was informed hours after by the Tour organization without mention of the substance. That night, Xavier Louy, director of the race, went to the hotel where Echavarri was and suggested to him that Delgado should withdraw. This was similar to the "Merckx affaire" in the 1969 Giro.
