Okumura Masanobu (1686 ??13 March 1764) was a Japanese print designer, book publisher, and painter. He also illustrated novelettes and in his early years wrote some fiction.

At first his work adhered to the Torii school, but later drifted beyond that. He is a figure in the formative era of ukiyo-e doing early works on actors and bijin-ga ('pictures of beautiful women').
