Baba Nobuharu (馬場 信春, 1514/15 – June 29, 1575), also known as Baba Nobufusa (馬場 信房), was a Japanese samurai of the Sengoku period. He was known as one of the "Twenty-Four Generals of Takeda Shingen".
Baba fought in the Kawanakajima campaigns, and led the Takeda army that besieged and destroyed Katsurayama, a major Uesugi clan stronghold in 1557. In 1573, he took part in the Battle of Mikatagahara, during which the troops under his command chased Tokugawa Ieyasu's army back to Hamamatsu fortress; upon seeing the gates open and braziers lit, Baba mistakenly suspected a trap, and did not press the fleeing army further. Following Takeda Shingen's death, Baba served his successor Takeda Katsuyori. He led the Takeda army's right-wing in the Battle of Nagashino in 1575, and was killed in combat during that engagement.
The Kōyō Gunkan states that Shingen often consulted Nobuharu on important matters. Prior to Nagashino, Nobuharu was reputed to have fought in 21 battles without receiving a single wound.
