Hachisuka Iemasa (蜂須賀 家政, 1558 – February 2, 1639) was a Japanese daimyō of the early Edo period.

Iemasa, the son of Hachisuka Masakatsu or Koroku, was the founder of the Tokushima Domain.

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.

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.
