Tenshō-in (天璋院, February 5, 1836 – November 20, 1883), also known as Atsuko (篤子), was the official wife of Tokugawa Iesada (徳川 家定), the 13th shōgun of the Tokugawa shogunate of Japan.

She was the daughter of Lady Oyuki and Shimazu Tadatake (島津忠剛), who was the head of the Imaizumi Shimazu (今和泉島津) branch of the Shimazu in Satsuma.

She was originally named Okatsu (於一) by her parents. When she was adopted by Shimazu Nariakira, her name was changed to Atsuko (篤子) or Atsu-hime (篤姫) ("Lady Atsu") and later to Fujiwara no Sumiko (藤原敬子) upon her adoption by Konoe Tadahiro.
