Mikail Antonovich Usov (February 20, 1883 in Kainsk, Novosibirsk Oblast, Russia – July 26, 1939 in Belokurikha, Altai Krai, Russia) was a Russian geologist and member of the Academy of Sciences of the USSR. He was the first native of Siberia to be elected.
He completed his studies at Tomsk Technological Institute (now Tomsk Polytechnic University) under Vladimir Obruchev and later served on the school's faculty.
Usov studied the geology of Siberia as well as adjacent regions in China and Mongolia and the gold producing regions of Kuznetsk Alatau and Transbaikal.
His most significant contributions to Russia were in his studies of the geological structure of the Kuznetsk Basin. His work enabled an evaluation of the coal reserves in the region and the prospects for developing industry around the coal.
Usov Street in Tomsk, on which the Geology Department of Tomsk Polytechnic University sits, is named for him.
