Ramos left Real Madrid when his contract expired on June 30 after failing to agree an extension, bringing an end to 16 years at the club.
"This is a big change in my life, a new challenge and it's a day I will never forget. I am very proud to be a part of this ambitious project, to be a part of this squad with so many great players. Paris Saint-Germain is a club that has already proven itself at the highest level. I want to continue to grow and improve at Paris and help the team to win as many trophies as possible."
