Hashiba Hidekatsu

 was a Japanese samurai, and the fourth son of the famed feudal warlord Oda Nobunaga and was adopted by Toyotomi Hideyoshi at a young age.
At the time of Nobunaga's death in 1582, Hidekatsu was at Kojima in Bizen Province. During the funeral, he held his birth father's mortuary tablet ("ihai"). Afterwards, Hidekatsu received Kameyama Castle in Tanba Province (modern day Kameoka, Kyoto Prefecture).
Shortly after Nobunaga's death, Hidekatsu assisted Hideyoshi during the Battle of Yamazaki, and defeated Akechi Mitsuhide. He also served Hideyoshi during the Battle of Komaki and Nagakute in 1584. Hidekatsu suddenly died in 1586, with many people believing that Hidekatsu was killed on the orders of Hideyoshi.
