The Echizen clan was a prominent samurai family in Japan during the feudal era, particularly known for their influence in the Echizen Province. They were part of the larger Minamoto clan and played a significant role in the political and military affairs of the region. The clan's power peaked during the late 16th century under the leadership of Tachibana Muneshige. The Echizen clan is often associated with the Echizen Matsudaira, a branch of the clan that ruled the province during the Edo period. They were known for their contributions to culture and governance, as well as their alliances with other powerful families, which helped maintain their status in the complex feudal hierarchy of Japan.
