Ban Naoyuki (塙 直之, 1567 – May 26, 1615), also known as Ban Dan'emon (塙 団右衛門), was a Japanese samurai general of the late Sengoku and early Edo periods. He first served as a retainer of Katō Yoshiaki, one of the "Seven Spears of Shizugatake", who went on to become lord of the Aizu domain, in Mutsu. Naoyuki served Lord Katō as a gunnery commander (teppō-taishō).
Naoyuki followed his lord during the invasion of Korea in the 1590s, and for his actions in combat there he was given a stipend of 350 koku. However, at the Battle of Sekigahara in 1600, he opposed Yoshiaki's orders and subsequently left his service. After that, he served several lords, including Kobayakawa Hideaki, Matsudaira Tadayoshi, and Fukushima Masanori; however, as his former lord Yoshiaki was a hindrance, Naoyuki entered the priesthood for a time.
