Original Nike football shirt Paris Saint-Germain 2017/18

The 2017–18 season was Paris Saint-Germain Football Club's 45th professional season since its creation in 1970, and its 44th consecutive season in the top-flight of French football. They broke the world transfer record by acquiring Neymar for a world record fee of €222 million.

The season was the first since 2011–12 without Maxwell, who retired after the 2016–17 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.
