Seki Kazumasa (関 一政, 1564 November 19, 1625) was a Japanese daimyo of the late Sengoku period through early Edo period, who was a retainer of the Oda and Toyotomi clans. His court title was Nagato no kami (長門守). Kazumasa took part in many of the major campaigns of the Toyotomi clan, serving as a yoriki under his brother-in-law Gamō Ujisato. In the early Edo Period, he served under the Tokugawa clan at the Sieges of Osaka. His domain of Kurosaka was confiscated in 1618, due to internal disturbances. Kazumasa died in 1625, but his nephew and adoptive son Ujimori was granted 5,000 koku and allowed to succeed to family headship as a high-ranking hatamoto.
