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.[1] He is also, along with Alain Léger, credited with the origin of the hypothesis that the series of infrared lines observed in numerous astrophysical objects are caused by emission from polycyclic aromatic hydrocarbons.[2] 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.[3] In 2018 he received the Shaw Prize in Astronomy[4].
