Aleksander Einseln (25 October 1931 – 16 March 2017) was an Estonian general, the Commander of the Estonian Defence Forces from 1993 to 1995 and previously a United States Army colonel.
Born in Estonia, his mother and he – barely in his teens – fled from the Red Army that was returning to occupy Estonia.
From 1950–1985, he served in the US Army, taking part in the Korean War, and as a Special Forces A-team commander in the Vietnam War.
In 1993, at the request of President Lennart Meri, he returned to Estonia to serve as the first Commander of the Estonian Defence Forces following the restoration of Estonia's independence.
