Viscount Niwa Nagahiro (丹羽長裕) (April 17, 1859 – July 29, 1886) was a Japanese daimyo of the early Meiji period who ruled Nihonmatsu han. The 9th son of Yonezawa lord Uesugi Narinori, he succeeded to the Nihonmatsu headship in 1868. Nihonmatsu had just lost in the Boshin War, and as one of the conditions for its surrender to the Imperial Japanese Army, Niwa Nagakuni, the previous daimyo, retired. In his place, his adopted son Nagahiro became daimyo, with Nihonmatsu reduced to 50,000 koku in its holdings (half of what it had previously held). After the domain system was abolished, Nagahiro became a shishaku (viscount) in the new kazoku system. He was succeeded by his birth brother Nagayasu (Uesugi Narinori's 11th son) in 1886.
