Matsudaira Katahiro (松平容衆, October 30, 1803 – April 20, 1822) was the 7th daimyō of Aizu Domain in Mutsu Province, Japan (modern-day Fukushima Prefecture).

His courtesy title was Higo-no-kami and Jijū, and subsequently raised to Sakonoe-gon-shōshō and his Court rank was Junior Fourth Rank, Lower Grade.

In 1813, he was received in formal audience by Shogun Tokugawa Ienari and given the courtesy title of Higo-no-kami.

He was wed to Moto-hime, the 15th daughter of Tokugawa Ienari, but died in 1822 without any heir.

This ended the line of direct descent from Tokugawa Hidetada begun by Hoshina Masayuki, the first daimyō of Aizu.
