Justin Jules (born 20 September 1986) is a French professional road bicycle racer, who most recently rode for UCI ProTeam Delko.^[4]

Born in Sartrouville, he is the son of Pascal Jules,^[5] a professional cyclist who was active during the 1980s – achieving one Tour de France stage victory in 1984^[6] – who died in a road traffic accident when Justin was just over a year old.

In 2008, Jules was sentenced to three years in prison for the manslaughter of his step-father in 2004.^[7] The sentence had been reduced due to a complicated upbringing and his step-father's troubles with alcoholism.^[8][9]

Jules has competed as a professional since the start of the 2011 season, as the La Pomme Marseille team he had joined from the Vendée U-Pays de la Loire team, successfully became a Continental team. Jules achieved his first professional victory at the 2011 Tour of Hainan, when he won the first stage of the race,^[10] and held the overall race lead for a week. After a spell with the Véranda Rideau-Super U squad in 2012, Jules rejoined La Pomme Marseille for the 2013 season.^[11] In his first race since rejoining, Jules won a bunch sprint for the honours in the season-opening race of the 2013 UCI Europe Tour, the Grand Prix d'Ouverture La Marseillaise; he managed to hold off the advances of Ag2r–La Mondiale's Samuel Dumoulin and Argos–Shimano rider Thomas Damuseau, for victory.^[8][12]
