The area of present-day Uonuma was part of ancient Echigo Province, with the name of Uonuma appearing in the Shoku Nihongi in an entry dated 702 AD. During the Edo period, the area was largely tenryō territory administered directly by the Tokugawa shogunate or part of the holdings of Aizu Domain. The area was greatly affected by the Tenpō famine of 1835-1837. After the Meiji restoration, the area was organised as part of Kitauonuma District, Niigata with the creation of the modern municipalities system. The modern city of Uonuma was established on November 1, 2004, from the merger of the towns of Horinouchi and Koide, and the villages of Hirokami, Irihirose, Sumon and Yunotani (all from Kitauonuma District).
