Takeda Nobuzane (河窪 信実) (died 1575) was a younger half-brother of Takeda Shingen, a preeminent daimyo (feudal lord) who vied for the control of Japan in the late stage of Sengoku, the "warring states" period.
Nobuzane was killed in an attack led by Sakai Tadatsugu and Kanamori Nagachika during the Battle of Nagashino.
