Jean-Loup Puget (born 7 March 1947) is a French astrophysicist. His current research interests lie in the Cosmic Microwave Background. Jean-Loup Puget and his collaborators reported the first identification of the Cosmic infrared background using COBE data.{{cite journal |author1=J.-L. Puget |author2=A. Abergel |author3=J.-P.

}} He is currently principal investigator of the HFI module of the Planck space mission.

He served two terms as director of the Institut d'astrophysique spatiale from 1998 to 2005.

He has been a member of the Académie des sciences (France) since 2002 and was awarded the Prix Jean Ricard in 1989. He received the COSPAR Space Science Award in 2014.

Jean-Loup Puget, Nazzareno Mandolesi and ESA Planck team were awarded 2018 Gruber Prize in Cosmology for their definitive measurements of the properties of our expanding universe.{{cite web|url=https://gruber.yale.edu/prize/2018-gruber-cosmology-prize|title=2018 Gruber Cosmology Prize|access-date=11 May 2018}} In 2018 he received the Shaw Prize in Astronomy.{{cite press release|date=2018-05-14|title=Announcement of The Shaw Laureates 2018|url=http://www.shawprize.org/en/shaw.php?tmp=5&twoid=79&threeid=278&fourid=554|publisher=The Shaw Prize Foundation|access-date=2018-09-11|archive-date=2018-10-07|archive-url=https://web.archive.org/web/20181007061234/http://www.shawprize.org/en/shaw.php?tmp=5&twoid=79&threeid=278&fourid=554|url-status=dead}}
