Yodo-dono

or , also known as , was a Japanese historical figure in the late Sengoku period. She was the concubine and the second wife of Japanese ruler Toyotomi Hideyoshi. As the mother of his son and successor Hideyori, she acted as Hideyori's guardian in the restoration of the Toyotomi clan after the fall of the Council of Five Elders, and alongside her son, led the last anti-Tokugawa shogunate resistance in the siege of Osaka.

She was the daughter of Oichi and sister of Ohatsu and Oeyo. When her two younger sisters became prominent members linked to the Tokugawa clan, she and her sisters became vital to maintaining the diplomatic relations between the two most powerful clans of the time, Toyotomi and Tokugawa. Her sister, Oeyo, was the wife of the second shogun, Tokugawa Hidetada, and matriarch of the successive shoguns' lineage, thus receiving the political title Omidaidokoro.
