Alaphilippe started the 2019 season in February with the Vuelta a San Juan and the Tour Colombia.
At the Vuelta a San Juan, he finished second overall and won two stages, and won the points classification and one stage at the Tour Colombia.
His first major race was Strade Bianche, which he won, beating out Astana rider Jakob Fuglsang in a kick up the final climb.
He finished 6th overall in Tirreno–Adriatico, earning a surprise victory on stage 6 despite leading out his team's designated sprinter Elia Viviani.
He then won his first Monument, in Milan–San Remo after attacking on the Poggio di San Remo and outsprinting Oliver Naesen and Michał Kwiatkowski.
He became UCI World ranking No.
1 as a result.
This was followed up by a near-miss of a podium place for the Amstel Gold Race, then three days later, a successful defense of his La Flèche Wallonne title that he had won in 2018.

Alaphilippe won the third stage of the Tour de France on 8 July, simultaneously earning himself the yellow jersey.
After losing the jersey on stage six to Giulio Ciccone, he regained it after the eighth stage, where he finished third.
He then won stage 13, the individual time trial, in Pau by beating Geraint Thomas by 14 seconds.
He kept the jersey until stage 19 after being dropped on the Col de l'Iseran.
It was his most successful Tour to date finishing in 5th place overall, winning 2 stages, wearing the yellow jersey for 14 stages and while he was not named the most combative rider after any individual stages, he did stand on the podium in Paris as the most combative rider for the entire Tour.
