Matsudaira Chikanori served as a bushō during the Sengoku and Azuchi-Momoyama periods. Chikanori was the fourth head of the Ogyū-Matsudaira family of Mikawa Province.
Chikanori was born as the son of Matsudaira Norikatsu, the third head of the Ogyū-Matsudaira. The Ogyū-Matsudaira were an illegitimate branch of the Matsudaira clan founded by Matsudaira Norimoto, the second son of Matsudaira Chikatada.
In 1530, Chikanori followed Matsudaira Kiyoyasu, serving valorously in an assault against the Kumagai clan based at Uri Castle in a strategic location connecting Mikawa to Tōtōmi Province.
In 1552, Chikanori incurred an attack at his base at Ogyū Castle by Matsudaira Tadashige of the Tōjō-Matsudaira family and fought against Tadashige. In the eighth month of 1555, upon orders of Imagawa Yoshimoto, Chikanori joined an assault on the base of the Oda clan at Kanie Castle. In 1556, he attacked Takiwaki Castle, the base of the Takiwaki-Matsudaira family. This resulted in the death in battle of Matsudaira Norikiyo and Matsudaira 乗遠 (father and son).
Around this time, he served as a guard for Tokugawa Ieyasu who was a hostage of the Imagawa clan and resided in Sunpu. On 1/8 of Kōji 3 (1557), Chikanori paid a visit to a noble named Yamashina Tokitsugu for a banquet. Thereafter, he maintained friendly relations with Tokitsugu including a gathering on 10/10 of Eiroku 11 (1568).
In 1575, Chikanori was the object of a surprise nighttime assault by Matsudaira Noritaka, the second son of 乗遠, and fled for safety to Owari Province.
