Mikhail Vasilevich Alekseev (15 November, 1857 - 8 October, 1918) was a Russian general and leader of anti-Bolshevik forces during the Russian Civil War.

The son of an army captain, he joined the Russian Army in 1876. He became Chief of staff of the Kiev Military District and commander of the XIII Corps in 1912. During World War I, he was Chief of staff of the Russian Southwest Army Group (Third, fourth, fifth, and Eighth Armies), and planned the Russian offensive into Galicia. He was appointed chief of staff of the Russian Army when the Tsar assumed full command in 1915. Alekseev urged the Tsar's abdication in 1917, and subsequently became Commander-In-Chief under the Provisional Government. Following the November Revolution, General Alekseev raised a 'volunteer' army in southern Russia, and became head of the White government after the death of General Kornilov in April 1918.
