Matsudaira Katasada (松平容貞, October 2, 1724 – October 26, 1750) was the 4th daimyō of Aizu Domain in Mutsu Province, Japan (modern-day Fukushima Prefecture).

His courtesy title was Sankonoe-gon-shō-shō and Jijū, and his Court rank was Junior Fourth Rank, Lower Grade.

He was received in formal audience by Shogun Tokugawa Yoshimune in 1735.

His courtesy title was promoted from Bungo-no-kami to Sankonoe-gon-shō-shō in 1740.

Due to peasant unrest, he was able to pay only one half of his required taxes in 1749, and died in 1750 at the age of 27.
