The 2018–19 season was Paris Saint-Germain Football Club's 46th professional season since its creation in 1970, and its 45th consecutive season in the top-flight of French football.
The season was the first since 2010–11 without Thiago Motta, who retired after the 2017–18 season.
French teams are limited to four players without EU citizenship. Hence, the squad list includes only the principal nationality of each player; several non-European players on the squad have dual citizenship with an EU country. Also, players from the ACP countries—countries in Africa, the Caribbean, and the Pacific that are signatories to the Cotonou Agreement—are not counted against non-EU quotas due to the Kolpak ruling.
