Takamatsu Domain was a feudal domain under the Tokugawa shogunate of Edo period Japan, in what is now Kagawa Prefecture on the island of Shikoku. It was centered around Takamatsu Castle, and was ruled throughout much of its history by a cadet branch of the Shinpan Matsudaira clan. Takamatsu Domain was dissolved in the abolition of the han system in 1871 and is now part of Kagawa Prefecture.
