The area of Ōita city was part of ancient Bungo Province, and the location of the Bungo Kokubun-ji and presumably the Bungo kokufu were located in this area. According to the Bungo no Kuni Fudoki, the name Ōita was given by Emperor Keiko when he visited this area in the late Kofun period; however, the main urban center was the port of Funai (府内) on the coast. During the Kamakura period, the Ōtomo clan was appointed shugo of the province, and made Funai their jōkamachi. By the Sengoku period, the Ōtomo has conquered most of Kyushu and had embraced Nanban culture, with Funai becoming a stronghold of the Kirishitan religion and western technology. However, the Ōtomo were destroyed by the Shimazu clan and after the establishment of the Tokugawa shogunate, their territories were divided, with Funai becoming the center of Funai Domain ruled by the Ogyū-Matsudaira clan.

The town of Ōita was established on May 1, 1889 with the creation of the modern municipalities system, and was raised to city status in 1911. On April 1, 1997, it was designated as a core city with greater local autonomy.

On January 1, 2005, the town of Notsuharu (from Ōita District) and the town of Saganoseki (from Kitaamabe District) were merged into Ōita.

Ōita has a mayor-council form of government with a directly elected mayor and a unicameral city council of 44 members. Ōita contributes 13 members to the Ōita Prefectural Assembly. In terms of national politics, the city is divided between the Ōita 1st district and Ōita 2nd district of the lower house of the Diet of Japan.
