Ii Naomasa (井伊 直政, March 4, 1561 – March 24, 1602) was a general under the Sengoku period daimyō, and later shōgun, Tokugawa Ieyasu.^[1] He led the clan after the death of Ii Naotora. He married Tobai-in, Matsudaira Yasuchika's daughter and adopted daughter of Tokugawa Ieyasu.

Ii Naomasa joined the ranks of the Tokugawa clan in the mid-1570s, rising swiftly through the ranks and became particularly famous after the Battle of Komaki and Nagakute, as he is recognized as one of the Four Guardians of the Tokugawa along with Honda Tadakatsu, Sakakibara Yasumasa, and Sakai Tadatsugu.

Ii Naomasa then eventually become the master of a sizable holding in Ōmi Province, following the Battle of Sekigahara in 1600.^[1] His court title was Hyōbu-dayū.
