Nabeshima Naozumi (?? ??, January 1, 1616 – April 5, 1669) was a Japanese daimyo of the early Edo period, who ruled the Hasunoike Domain in Hizen Province (modern-day Saga Prefecture).
He was the son of Nabeshima Katsushige, and was a viable candidate for succession to the lordship of the Saga Domain upon the death of his brother Tadanao (Naozumi married Tadanao's widow); however, this plan was unsuccessful.
Naozumi was instead granted 52,000 koku in Hizen Province, and became the first daimyo of Hasunoike.
