Alexander Ivanovich Mavrichev (Russian: Александр Иванович Мавричев; 21 July 1901 – 12 September 1974) was a Soviet Army major general.

Mavrichev and his division were encircled in the first weeks of the war, and he spent several months making his way back to Soviet lines.

Mavrichev became chief of communications of the engineering and construction units of the 5th Army in April 1920 and from September of that year studied at the infantry department of the Siberian Higher Military School.

Upon graduation in April 1922, Mavrichev became a company commander of the 62nd Rifle Regiment of the People's Revolutionary Army of the satellite Far Eastern Republic.

From May of that year he served as chief and then assistant chief of the 32nd Blagoveshchensk Cavalry School of the GPU Troops of the Far Eastern District, and in December returned to army units to become a company commander of the 62nd Novorossiysk Rifle Regiment, now part of the 21st Rifle Division of the Siberian Military District.

On 1 July, Mavrichev and the remnants of the division left the encirclement with a group led by 3rd Army commander General Vasily Kuznetsov, heading towards Rogachev and Bykhov.

Mavrichev managed to escape with six others and joined the partisan detachment led by former 64th Rifle Division commander Colonel Sergey Iovlev.
