Mineyama Domain () was a fudai feudal domain under the Tokugawa shogunate of Edo period Japan. It was located in Echigo Province, in the Hokuriku region of Honshà «. The domain was centered at Mineyama, located in modern-day Mineoka in Niigata Prefecture.
The domain was created in 1634 (Kan'ei 11) when the lord of Nagaoka Domain Makino Tadanari () distributed 6,000 koku of territory around Mineyama to his fourth son Makino Sadanari (). As the new domain had less than 10,000 koku, Sadanari was designated as a hatamoto samurai instead of a daimyo.
In 1863 (Bunkyà « 2), the Tokugawa shogunate formally recognized Mineyama as a feudal domain with 11,000 koku. Unlike many other feudal subjects, the lord Makino Tadayasu () was exempted from the requirement of spending time in the capital Edo as dictated by the Sankin-kà Âtai policy. The administrative center of the domain was located at Mineyama Jinya.
During the Boshin War, Mineyama Domain, along with the other domains under the Makino clan, initially joined the à Âuetsu Reppan Dà Âmei. It submitted to the new Meiji government in August 1868 (Keià  4), and subsequently sent troops to aid the latter's conquest of Shà Ânai Domain. In 1870 (Meiji 3), the name of the domain was changed to Mineoka () to avoid being confused with the Mineyama Domain in Tango Province. In the following year, the domain was abolished and became a part of Niigata Prefecture.
As with most domains in the han system, Mineyama Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.
