Hachisuka Iemasa

was a Japanese daimyō of the early Edo period. Iemasa, the son of Hachisuka Masakatsu or Koroku, was the founder of the Tokushima Domain. He was one of some daimyo who have bad terms with Ishida Mitsunari.

His father was a retainer of Toyotomi Hideyoshi. But later Iemasa served both Oda Nobunaga and Hideyoshi, taking part in the Battle of Yamazaki in 1582, invasion of Shikoku in 1585, and Hideyoshi's Korean campaign from 1592 to 1598. After Hideyoshi gained control of Shikoku, Awa Province was given to Hachisuka Iemasa along with Awaji Island. He and his family were appointed as lords of the fief with an income of 257,000 koku; the family ruled until the end of the Edo period.

In 1600, Iemasa fought on the side of Tokugawa Ieyasu at the Battle of Sekigahara, and was allowed to retain his fief for his service there.
