Ukita Hideie (宇喜多 秀家, 1572 – December 17, 1655) was the daimyō of Bizen and Mimasaka Provinces (modern Okayama Prefecture), and one of the council of Five Elders appointed by Toyotomi Hideyoshi.

Hideie's father Ukita Naoie was daimyō of Bizen province and initially opposed, but later sided with Oda Nobunaga and Toyotomi Hideyoshi.

Hideyoshi raced back to Kyoto, leaving the Ukita clan in charge of Bizen, Mimasaka and newly taken parts of Bitchū Province.

Later in 1597, Hideie became a "Chief Commander Army of the Left" in the Second Korean campaigns, returning in 1598 to serve as one of Hideyoshi's five counselors (Council of Five Elders) along with Maeda Toshiie, Uesugi Kagekatsu, Mōri Terumoto, and Tokugawa Ieyasu.

Tadatsune and Hideie's relative Maeda Toshinaga, however, negotiate with Ieyasu and he escaped the death penalty, and he was confined in Mt.

Gohime, (Hideie's wife) sought refuge with the Maeda clan and was able to correspond and send gifts (rice, sake, clothing) to her husband and sons from there.

His wife had died, the Toyotomi were defeated, there was no place to return to, his sons had fathered children on Hachijojima, and the Shogunate was to be inherited by members of the Tokugawa clan.

There is no evidence to suggest that Hideie fathered any further children himself, but many of his sons' descendants emigrated back to the Japanese mainland when a full pardon was granted at the end of the Edo era.
