The Kyōgoku clan (京極氏, Kyōgoku-shi^?) were a Japanese daimyo clan which rose to prominence during the Sengoku and Edo periods. The clan descend from the Uda Genji through the Sasaki clan. The name derives from the Kyōgoku quarter of Kyoto during the Heian period.

The Kyōgoku acted as shugo (governors) of Ōmi, Hida, Izumo and Oki Provinces in the period before the Ōnin War.

A period of decline in clan fortunes was mitigated with the rise of the Tokugawa clan. Members of the clan were daimyo of territories on the islands of Kyūshū and Shikoku during the Edo period. Under the Tokugawa shogunate, the Kyōgoku were identified as tozama or outsiders, in contrast with the fudai or insider daimyo clans which were hereditary vassals or allies of the Tokugawa.

At the fall of the Tokugawa shogunate, the Kyōgoku had been enfeoffed at Marugame and Tadotsu in Sanuki, Toyooka in Tajima, and Mineyama Domain in Tango Province. A branch of the Kyōgoku was ranked among the kōke.
