}}{{nihongo|Hiroshi Okamura|岡村博|Okamura Hiroshi|November 10, 1905 – September 3, 1948}} was a Japanese mathematician who made contributions to analysis and the theory of differential equations. He was a professor at Kyoto University.^[1]^[2]

He discovered the necessary and sufficient conditions on initial value problems of ordinary differential equations for the solution to be unique.^[3] He also refined the second mean value theorem of integration.
