Matsudaira Chikasada served as a bushō during the Sengoku period.  Chikasada served as the second head of the Ōkusa-Matsudaira based at Okazaki Castle in Mikawa Province.  

Chikasada was born as the son of Matsudaira Mitsushige, the founder of the Ōkusa-Matsudaira.  Mitsushige was the fifth son of Matsudaira Nobumitsu of the Iwatsu-Matsudaira.  Until 1524, when Okazaki Castle was captured by Matsudaira Kiyoyasu, the Ōkusa-Matsudaira were called the Okazaki-Matsudaira.

There is a lack of authenticated materials detailing his movements, but, in a jointly sealed covenant from the Daiju Temple dated in 1501 appears the name of Okazaki Sama-no-jō (Chikasada).  It is surmised that he inherited the headship of the clan during this period, or else was killed in action during the invasion of Mikawa Province by Imagawa Ujichika and Ise Shinkurō Nagauji (later known as Hōjō Sōun, a sengoku daimyō and founder of the Gohōjō clan) from 1506 to 1509.

This is consistent with a letter sent by his younger brother, Matsudaira Masayasu (Nobusada), in 1511 after the death of his father, Mitsushige, in 1508.

Chikasada died without an heir so the headship of the clan was inherited by Masayasu.  According to one theory, Masayasu was the son of Saigō Yoritsugu, the former owner of the territory in Okazaki and Masayasu’s succession was connected to the marriage by Mitsushige to the daughter of Yoritsugu.

His grave is at the Dairin Temple in Okazaki but the year of his demise is unknown.
