The area of present-day Ōdate was part of ancient Dewa Province, and numerous Jomon period ruins have been found within city limits. Populated by Emishi tribes, it remained outside of the control of the Yamato court until well into the Heian period. The first mention of "Hinai", the area of central Ōdate is in the Nihon Sandai Jitsuroku in an article on the Gangyo War of 878, in which Hinai is listed as one of the villages under the control of Akita Castle. During the Edo period, the area came under the control of the Satake clan, who ruled the northern third of the province from Kubota Domain, and who maintained a secondary fortification at Ōdate Castle. The castle was destroyed during the Boshin War. .

After the start of the Meiji period, the area became part of Kitaakita District, Akita Prefecture in 1878. The town of Ōdate was established on April 1, 1889 with the establishment of the modern municipalities system. During the Meiji period, the discovery of "black ore" (sphalerite and galena - a mixture of zinc, lead, gold, silver, and other precious metals), led to the development of numerous mines in the area, including the Hanaoka mine; however, the deposits were depleted by the mid-Shōwa period.

Ōdate was raised to city status on April 1, 1951. On June 20, 2005, the towns of Hinai and Tashiro (both from Kitaakita District) were merged into Ōdate, almost doubling the city's area.

Ōdate has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 26 members. The city contributes three members to the Akita Prefectural Assembly. In terms of national politics, the city is part of Akita District 2 of the lower house of the Diet of Japan.

The economy of Ōdate is based on agriculture, forestry and seasonal tourism.
