The 1972–73 season was Paris Saint-Germain F.C.'s first season after its split from Paris FC. It was also PSG's 1st and last season in the Championnat National. Robert Vicot was named coach replacing Phelipon. He began his coaching career at PSG with the Under-18s, tooking them to the semi-final of the Coupe Gambardella. During this season he was the sole coach of the club. Under Robert Vicot's charge, PSG proved to be just too good for third division and the club quickly took the second spot, missing out on promotion by little. However, the first, Quevilly, officially dissolved due to financial problems at the end of the season and consequently the club was disqualified. PSG, second in the table, took their place in the second division. During this season, the reserve team won its second Coupe de Paris.
