Sir Antony James Beevor (born 14 December 1946) is a British military historian. He has published several popular historical works, mainly on the Second World War, the Spanish Civil War, and most recently the Russian Revolution and Civil War.

Educated at Abberley Hall School, Winchester College, and the Royal Military Academy Sandhurst, Beevor commanded a troop of tanks in the 11th Hussars in Germany before deciding in 1970 to leave the army and become a writer. He was a visiting professor at Birkbeck, University of London, and the University of Kent.

His best-selling books, Stalingrad (1998) and Berlin: The Downfall 1945 (2002), have been acclaimed for their detailed coverage of the battles between the Soviet Union and Germany, and their focus on the experiences of ordinary people. Berlin proved very controversial in Russia because of the information it contained from former Soviet archives about the mass rapes carried out by the Red Army in 1945.

Beevor's works have been translated into many languages and have sold millions of copies. He has lectured at numerous military headquarters, staff colleges, and establishments in Britain, the US, Europe, and Australia. He has also written for many major newspapers.
