Kapiton Yakovlevich Ushkov (Russian: Капитон Ушков) (1813-1868) was a Russian serf who became a major chemical industrialist in Tartarstan.
He was born in Bonduga, a village near Yelabuga, in Tartarstan. Bonduga was subsequently renamed Mendeleyevsk. Ushkov discovered that the raw materials for potassium bichromate, a chemical used in the dying process was to be found locally, and so he established a plant for its production in the village of Kokshan.
His family included Peter Ushkov (1840—1898) and Konstantin K. Ushkov (1850—1918).
