Sanofi S.A. (Euronext: SAN, NYSE: SNY, LSE: 0I42, FWB: SNW) is a multinational pharmaceutical company headquartered in Paris, France, the world's fourth-largest by prescription sales. Sanofi primarily engages in the research and development, manufacturing and marketing of pharmaceutical products for sale in the prescription market, and also develops over-the-counter medication.

Formed as Sanofi-Aventis in 2004 by the merger of Aventis and Sanofi-Synthélabo, the company dropped the -Aventis suffix of its name on 6 May 2011 after receiving approval at its AGM. The reason given by the company for the change was to make its name easier to pronounce in countries such as China.

In June 2010, Sanofi and the Charite University of Berlin signed a cooperation agreement for the research and development of medicines and therapies.
