Aleksei Innokentievich Antonov (Russian: Алексей Иннокентьевич Антонов; 9 September 1896 – 16 June 1962) was a General of the Soviet Army, awarded the Order of Victory for his efforts in World War II.

In December 1942, he became Deputy Chief General Staff of the combined Soviet forces and Head of the Operations Directorate, a pivotal role within the Stavka.

In February 1945, Vasilevsky was appointed as the commander of 3rd Belarusian Front, and Antonov finally became the formal leader of Soviet General Staff.

Richard Overy writes of him at this time: Vasilevsky came to rely on one subordinate above all others: the chief of operations, General Aleksei Antonov.

Instead of rushing off to report to Stalin when he arrived in Moscow, he spent the first week familiarizing himself thoroughly with the General Staff and the state of the front.

He was firm, caustic, slow to praise and a tough taskmaster, but the rigorous regimen that he imposed on his staff won their respect.
