Matsudaira Yoritoshi (松平 頼聰) (September 6, 1834 – October 17, 1903) was a Japanese daimyō of the late Edo period, who ruled the Takamatsu Domain.
Under his leadership, Takamatsu forces supported the security operations of the Tokugawa shogunate in the Kyoto area.
During the Kinmon Incident, Takamatsu troops helped defend the imperial palace.
His forces took part in the Battle of Toba–Fushimi, and in response, the imperial court stripped him of rank and title.
Yoritoshi then put himself under domiciliary confinement, and had a senior retainer executed; this led to an imperial pardon.
