The Imperial Prize of the Japan Academy (恩賜賞・日本学士院賞?) was a prestigious honor conferred by the Imperial Academy from 1911 through 1945. The award was presented to non-members in recognition of their academic theses, books, and achievements.
In the post-war period, the Imperial Academy was renamed the Japan Academy; and the name of this prize was changed accordingly. The substantially similar Japan Academy Prize was awarded after this 1947 evolution.
