Shibata Nagaatsu

Shibata Naganori (新発田 長敦, 1538 – 1580), usually known as Shibata Nagaatsu (died 1580), was a Japanese military commander who served under the warlord Uesugi Kenshin, one of the Twenty-Eight Generals of Uesugi.

The son of Shibata Tsunasada and the elder brother of Shibata Shigeie, Naganori served under Kenshin from the latter's earliest campaigns. During the Ōtate no Ran, the succession struggle that followed Kenshin's death, Naganori supported Kenshin's son Kagekatsu. Naganori died of illness in 1580.
