Kariya han was an Edo period domain located in Mikawa province. A small domain with a kokudaka of 23,000 koku, it was ruled by a number of different clans over the course of the 1600s-1740s; from the 1740s until the end of the Edo period, the domain was ruled by the Doi clan.
Among the domain's many lords was, for a brief time in 1649 to 1651, Matsudaira Sadamasa, a nephew of Tokugawa Ieyasu. After protesting against policies enacted in the aftermath of Shogun Tokugawa Iemitsu's death in 1651, Sadamasa was declared by the shogunate unfit for rule, and was attaindered.
