Yodo-dono (淀殿) or Yodogimi (淀君) (1569–1615) was a prominently placed figure in late-Sengoku period. She was a concubine and second wife of Toyotomi Hideyoshi, who was then the most powerful man in Japan. She also became the mother of his son and successor, Hideyori. She was also known as Lady Chacha (茶々). After the death of Hideyoshi, she took the tonsure, becoming a Buddhist nun and taking the name Daikōin (大広院).
She was the eldest of three daughters of the Sengoku period daimyo, Azai Nagamasa. Her mother, Oichi was the younger sister of Oda Nobunaga. Yodo-dono's middle and younger sister is Ohatsu and Oeyo, also known as Ogō. After Nagamasa's death, Toyotomi Hideyoshi became the adoptive father and protector of Chacha. Her status changed when she became his concubine. Her status and her name were changed again when Yodo-dono became the mother of a male heir for the aging Taiko.
