Minamoto no Michichika (源 通親^?, 1149 – November 7, 1202) was a Japanese noble and statesman of the late Heian period and early Kamakura period. Serving in the courts of seven different emperors, he brought the Murakami Genji to the peak of their success. He is also commonly known as Tsuchimikado Motochika (土御門 通親^?), and in Sōtō Zen buddhism as Koga no Michichika (久我 通親^?).

Born the heir of the Murakami Genji branch of the Minamoto clan in 1149, and in 1158 was granted the lower junior fifth rank (従五位下^?), via the Minamoto family head's prerogative to thus promote one individual each year. The Murakami Genji had previously enjoyed prosperity as the maternal relatives of Emperor Horikawa, but after this were pushed back by descendants of Fujiwara no Kinsue's branch of the Fujiwara clan, the Kan'in-ryū (閑院流^?). Michichika's father Masamichi served Bitokumon-in during Emperor Toba's cloistered rule, but changed his role under the cloistered rule of Emperor Go-Shirakawa. In 1168, when Go-Shirakawa's wife Taira no Shigeko () became kōtaigō, Masamichi became director of the Kōtaigō's Quarters (皇太后宮大夫^?). Michichika was permitted entry into the court along with Emperor Takakura's ascension in the same year, serving as a close aid to the young emperor. Michichika's first wife was a daughter of the daijō-daijin Fujiwara no Tadamasa (), but he soon took a daughter of Taira no Norimori or Michimori as his second wife, strengthening his ties with that powerful clan.
