Kokura Domain was a feudal domain under the Tokugawa shogunate of Edo period Japan, in what is now eastern Fukuoka Prefecture. It was centered around Kokura Castle in what is now Kitakyushu, Fukuoka and was ruled by the fudai daimyō Ogasawara clan for much of its history. In the Bakumatsu period and first years of the Meiji period, it was briefly known as Kawara Domain (香春藩) and then Toyotsu Domain (豊津藩).
