Miyazu Domain (宮津藩, Miyazu-han) was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Tango Province in what is now the northern portion of modern-day Kyoto Prefecture. It was centered around the Miyazu Castle which was located in what is now the city of Miyazu, Kyoto and was controlled by a number of fudai daimyō clans through its history. ^[1][2][3]

From the Muromachi period, Tango Province had been under the control of the Isshiki clan. However, in the Sengoku period, Toyotomi Hideyoshi placed the province under the control of Hosokawa Tadaoki. Following the Following the Battle of Sekigahara, Tokugawa Ieyasu awarded the entire province of Tango to Kyōgoku Takatomo, who established Miyazu Domain. To ensure the succession of his line, Kyōgoku Takatomo gave 35,000 koku of his holdings to his third son, Kyōgoku Takamitsu, and established a cadet branch of the clan at Tango-Tanabe Domain, and 10,000 koku to his grandson, Kyōgoku Takamichi, who established Mineyama Domain. This proved to be a wise decision, his grandson Kyōgoku Takakuni was charged with misconduct and poor governance by the Tokugawa shogunate and reduced to hatamoto status in 1666.

After a couple years as a tenryō territory, Miyazu was revived for Nagai Nagayuki, formerly of Yodo Domain. His son, Nagai Naonaga was murdered by Naito Tadakatsu of Toba Domain in 1680. As he was without heir, Miyazu was assigned to the Abe clan, Okudaira clan and then to a cadet branch of the Matsudaira clan, the Honjō-Matsudaira, who ruled from 1758 to the Meiji restoration. The 6th daimyō, Matsudaira Munehide served as Kyoto shoshidai, and rōjū during the tumultuous Bakumatsu period. The domain reluctantly fought for the shogunate during Battle of Toba-Fushimi at the opening of the Boshin War, but switched sides shortly after the defeat of Tokugawa forces. Miyazu Domain became "Miyazu Prefecture" in 1871, then part of "Toyooka Prefecture" before becoming part of Kyoto Prefecture in 1876. The Honjo-Matsudaira clan was later ennobled with the kazoku peerage title of shishaku (viscount).

As with most domains in the han system, Miyazu Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.^[4][5]
