Nagashino Castle (長篠城, Nagashino-jō^?) was a Sengoku period Japanese castle located in what is now Shinshiro, eastern Aichi Prefecture, Japan. It is noteworthy as the site of the crucial Battle of Nagashino between the combined forces of Tokugawa Ieyasu and Oda Nobunaga against Takeda Katsuyori in 1575.

In 1508, Imagawa Ujichika, ruler of Suruga and Totomi Provinces, ordered his vassal Suganuma Motonari to build a castle in Shitara County, Mikawa Province to guard the western approaches to his domains.

The castle came under the control of Tokugawa Ieyasu in 1573, who placed former Takeda vassal Okudaira Sadamasa in control. Following skirmishes with the increasingly bellicose Takeda clan to the north, the castle’s defenses were strengthened. The Takeda invaded Mikawa Province in force in 1575, and laid siege to the castle. In the subsequent Battle of Nagashino, the combined forces of Tokugawa Ieyasu and Oda Nobunaga brought a total force of 38,000 men to relieve the siege on the castle by Takeda Katsuyori. Of Takeda's original 15,000 besiegers, only 12,000 faced the Oda-Tokugawa army in this battle. Seeking to protect his arquebusiers from the Takeda cavalry, Nobunaga built a number of wooden stockades, behind which his gunners attacked in volleys. By mid-afternoon on the day of the battle, the Takeda broke and fled, after losing a great number of men, including eight the famous 'Twenty-Four Generals' Katsuyori had inherited from Takeda Shingen. This use of gunfire was a turning point in the history of samurai warfare. After the battle, the castle was allowed to fall into ruin.
