The Alexandrov Ensemble choir (established Moscow 1926) is the choir of the Alexandrov Ensemble.
It has for most of its history been a male-voice choir of tenors and basses, based in Moscow and directed and conducted by Alexander V. Alexandrov from 1926 to 1946, by his son Boris A. Alexandrov from 1946 to 1987, and by various directors up to the present. It has always consisted of Soviet and then Russian Red Army personnel, and has been held to represent that army at home and abroad. Since the 1990s, female army personnel have occasionally been included in the choir as sopranos. Since 2007 boy sopranos and altos from the associated choir school have joined the choir for some of the time.
On December 25, 2016, a plane containing 92 people, including over 60 members of the choir, crashed while en route to Latakia, Syria.
