Miura District was one of the ancient subdivisions of Sagami Province, covering all of Miura Peninsula. It was under the control of the Miura clan from the late Heian period through the Sengoku period, and was held as tenryo territory administered by the Shogun under the Tokugawa Shogunate of the Edo period. After the Meiji Restoration, it was established as a district under the cadastral reform of 1878, with a district office built near what is now Shioiri Station.
