Tsugaru Yasuchika (津軽 寧親, March 8, 1765 – July 30, 1833) was the 9th daimyō of Hirosaki Domain in northern Mutsu Province, Honshū, Japan (modern-day Aomori Prefecture).
Yasuchika implemented many of the reforms initiated by Nobuakira to restore prosperity to the disaster-prone domain, including having many of his samurai turn to part-time farming to maintain their revenues.
In 1805, the Shogunate charged Tsugaru Domain with the responsibility of maintaining the security of a portion of Ezo, an area considered loosely at the time to encompass present-day Hokkaidō, Karafuto and the southern Kurile Islands.
The kokudaka of the domain was further increased to 100,000 koku in 1808, and in 1809 Kuroishi was raised to a full han status.
In 1825, Yasuchika turned rule of the domain over to his second son and went into retirement, spending his time writing haiku poetry.
