Sir Marc Aurel Stein (usually known as Aurel Stein) KCIE, FBA (Hungarian: Stein Márk Aurél) (26 November 1862 – 26 October 1943) was a Hungarian-British archaeologist, primarily known for his explorations and archaeological discoveries in Central Asia. He was also a professor at various Indian universities.

Stein was born in Budapest into a Jewish family. His parents had him and his brother, Ernst Eduard, baptised as Lutherans, while his parents and sisters remained Jews (a common way at the time to increase the chance of one's sons being successful). He later became a British citizen and made his famous expeditions with British sponsorship.
