Tōyama Tomoyoshi (遠山友禄, October 20, 1819 – April 4, 1894) was the 12th and final daimyō of Naegi Domain under the Bakumatsu period Tokugawa Shogunate of Japan.

[1] The following year, the Namamugi Incident occurred, in which a British merchant was killed by the retinue of Shimazu Hisamitsu near Yokohama.

He soon submitted to the new Meiji government and was asked to dispatch troops to guard Iwakura Tomomi and the imperial army advancing along the Nakasendō through Shinano Province.

Not having an heir, he adopted a son of Oda Nagayasu of Shibamura Domain to succeed the Tōyama family line.

In 1870, he also missed an order that all Buddhist temples in Naegi, including the clan's bodaiji of Unrin-ji were to be destroyed, and that only Shinto shrines would be permitted in his domain.
