Mahmoud Khayami, CBE, KSS, GCFO (7 January 1930 – 28 February 2020) was an Iranian industrialist and philanthropist of French nationality.

One of the leading champions of Iran's industrialization of the 1960s–70s, he began the production of the popular Peykan cars in 1967, based on cooperation with the Hillman-Hunter company of England which provided the model for it.

By 1979 Iran National and its affiliated enterprises employed over 20,000 workers in Tehran, Mashhad, and Tabriz.

Although Khayami has died, his family is still involved in the automotive industry, primarily in dealership ownership of one of their previous international partners Mercedes-Benz, most notably in Berkshire, England, and Southern California where they operate Mercedes-Benz of Anaheim in the city of Anaheim, Orange County.

His philanthropic work (now performed largely through the Khayami Foundation) was recognised in 2004 when he was invested as a Knight of the Pontifical Order of Pope Saint Sylvester by Pope John Paul II, and in 2006 when he was invested as a Knight Commander of the Royal Order of Francis I by Prince Carlo, Duke of Castro.
