Sengoku Hidehisa (仙石 秀久; February 20, 1552 − June 13, 1614), childhood name Gonbei (権兵衛) was a samurai warrior of the Sengoku period and the Edo period. He was the head of the Komoro Domain in Shinano Province. Hidehisa is also credited with being the man who captured the legendary outlaw hero "Ishikawa Goemon".

According to his family records, Hidehisa was the fourth son of his family, a low ranking samurai family in the Saitō clan. He was adopted out to another family at a young age, but eventually his older brothers died of illness and he was recalled to inherit his family name. During Mino Campaign, his clan was destroyed by Oda Nobunaga and he was captured during the assault.

He then became a member of the Oda clan and was ordered to serve under Kinoshita Tōkichirō (the eventual Toyotomi Hideyoshi). Hidehisa took part in most of the Oda clan's military actions afterwards. Slowly but steadily he rose up through the ranks.

Hidehisa is generally described as a brave and skillful warrior in his early days with Nobunaga; he was often at the front lines of the Oda clan's military operations. He also appears to have inherited some of Hideyoshi's charisma, as he was able to avoid getting himself killed despite ending up several times in situations that would normally have boded poorly for most samurai.

In 1581, he was made the daimyō of Awaji Island at Sumoto Castle.

In 1583, he was defeated in the Battle of Hiketa against Chosokabe Motochika.

In 1585, he participated in Hideyoshi's successful campaign in Shikoku against Chosokabe clan.

In 1587, he was given charge to lead the campaign on Kyushu with two other daimyō: Chōsokabe Motochika and Sogō Masayasu. However, they were crushed in the Battle of Hetsugigawa by the Shimazu. Sogō Masayasu perished along with Chōsokabe Motochika's heir, Nobuchika. Hidehisa was accused of charging ahead too soon and then fleeing at the first sight of trouble. After he returned to Hideyoshi, he was stripped of his title, land, and sent into exile.
