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.
