The area of present-day Oga was part of ancient Dewa Province, dominated by the Satake clan during the Edo period, who ruled Kubota Domain under the Tokugawa shogunate. The village of Funagawa was established with the establishment of the modern municipalities system on April 1, 1889 and became the town of Funagawaminato on October 24, 1894. The city of Oga was created on March 31, 1954, by the merger of the town of Funagawaminato with the four neighboring villages of Wakimoto, Iriai, Ogatanaka and Toga.

On March 22, 2005, the town of Wakami was merged into Oga.^{[citation needed]}
