Miura District (三浦郡, Miura-gun) is a district located in Kanagawa Prefecture, Japan.
As of 2009, the district has an estimated population of 32,333 and a density of 1,900 persons per km2.
It was under the control of the Miura clan from the late Heian period through the Sengoku period, and was held as tenryō territory administered by the shōgun 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.
As of 2009, this leaves only the town of Hayama as the sole remaining portion of Miura District.
