Tsugaru Nobuhisa (津軽 信寿, June 22, 1669 – March 10, 1746) was the 5th daimyō of Hirosaki Domain in northern Mutsu Province, Honshū, Japan (modern-day Aomori Prefecture).

On his accession to the lordship at the age of 43, he proclaimed seven days of mourning, followed by elaborate ceremonies enshrining his father at the Shinto shrine of Takateru Jinja in Hirosaki.

This issue would resurface again in 107 years with the attempt in 1821 by Nanbu samurai to assassinate the Tsugaru daimyō in the "Sōma Daisaku Incident.

On the other hand, Nobuhisa surrounded himself with sycophants at his Edo residence and continued to live a life of profligate luxury.

Word of this reached the ears of shōgun Tokugawa Yoshimune, and influenced the sections of the Kyōhō Reforms emphasizing the need for frugality.
