Saito Tatsuoki (斎藤 龍興 Saitō Tatsuoki) (1548 - August 14, 1573) was a daimyo in Mino province during the Sengoku period. He was a son of Saito Yoshitatsu.
Tatsuoki succeeded his father at the age of 14. He was, however, an incapable ruler ulike his grandfather and father. He lost to Oda Nobunaga in 1564 but survived, yet the Saito family were no longer players in the Sengoku wars.
