The Fukui Domain , also known as the Echizen Domain , was a domain (han) of the Tokugawa Shogunate of Japan during the Edo period from 1601 to 1871.

Fukui Castle is a flatland-style castle located in what is now the city of Fukui, Fukui Prefecture, Japan. During the Edo period, it was the headquarters of a branch of the Matsudaira clan, who were hereditary daimyō of Fukui domain under the Tokugawa shogunate. The castle was also known by the name of Kitanoshō Castle , after an earlier castle built by Shibata Katsuie, over whose ruins it is partly built.
