Ohama Kagetaka (小浜景隆, 1540-1597) was a Japanese pirate during the latter part of the Sengoku period and the Azuchi-Momoyama period of Japan. He operated in the Shima Province area (now part of Mie Prefecture), later becoming a general leading naval forces for both Takeda Shingen and Tokugawa Ieyasu before his death in 1597 at the age of 57.
Ohama operated as a pirate chief in the area that is present-day Obama in Toba, Mie Prefecture. He held great power in the Ise Bay area as well as being very influential over the Kitabatake clan which held the governorship of the Ise Province. Ohama controlled the Kitabatake family's pirates due to having an atakebune, using them to defeat Kuki Yoshitaka who had allied with Oda Nobunaga in his bid to unify Shima Province. He subsequently overran Ise Bay.
