Oda Nagamasu (織田 長益?, 1548 – January 24, 1622) was a Japanese daimyo who lived from the late Sengoku period through the early Edo period. Also known as Urakusai (有楽斎), he was a brother of Oda Nobunaga. Nagamasu converted to Christianity in 1588 and took the baptismal name of John.
Nagamasu was an accomplished practitioner of the tea ceremony, which he studied under the master, Sen no Rikyū. He eventually started his own school of the tea ceremony.
Nagamasu divided his fief between his sons Nagamasa and Hisanaga. Nagamasa founded the Kaijū-Shibamura Domain, while Hisanaga became lord of the Yanagimoto Domain.
