Luc Montagnier (US: MON-tən-YAY, MOHN-tahn-YAY, French: [lyk mɔ̃taɲe]; 18 August 1932 – 8 February 2022) was a French virologist and joint recipient, with Françoise Barré-Sinoussi and Harald zur Hausen, of the 2008 Nobel Prize in Physiology or Medicine for his discovery of the human immunodeficiency virus (HIV). He worked as a researcher at the Pasteur Institute in Paris and as a full-time professor at Shanghai Jiao Tong University in China.
In 2017, Montagnier was criticised by other academics for using his Nobel prize status to "spread dangerous health messages outside of his field of knowledge". During the COVID-19 pandemic, Montagnier promoted the conspiracy theory that SARS-CoV-2, the causative virus, was deliberately created and escaped from a laboratory. Such a claim has been rejected by other virologists.
