In the 2019 Paris–Nice, four jerseys were awarded. The general classification was calculated by adding each cyclist's finishing times on each stage. Time bonuses were awarded to the first three finishers on all stages except for the individual time trial: the stage winner won a ten-second bonus, with six and four seconds for the second and third riders respectively. Bonus seconds were also awarded to the first three riders at intermediate sprints – three seconds for the winner of the sprint, two seconds for the rider in second and one second for the rider in third. The leader of the general classification received a yellow jersey. This classification was considered the most important of the 2019 Paris–Nice, and the winner of the classification was considered the winner of the race.

The second classification was the points classification. Riders were awarded points for finishing in the top ten in a stage. Unlike in the points classification in the Tour de France, the winners of all stages were awarded the same number of points. Points were also won in intermediate sprints; three points for crossing the sprint line first, two points for second place, and one for third. The leader of the points classification was awarded a green jersey. There was also a mountains classification, for which points were awarded for reaching the top of a climb before other riders. Each climb was categorised as either first, second, or third-category, with more points available for the more difficult, higher-categorised climbs. For first-category climbs, the top seven riders earned points; on second-category climbs, five riders won points; on third-category climbs, only the top three riders earned points. The leadership of the mountains classification was marked by a white jersey with red polka-dots. The fourth jersey represented the young rider classification, marked by a white jersey. Only riders born after 1 January 1994 were eligible; the young rider best placed in the general classification was the leader of the young rider classification. There was also a classification for teams, in which the times of the best three cyclists in a team on each stage were added together; the leading team at the end of the race was the team with the lowest cumulative time.
