Momoyama Harue (桃山 晴衣, 1939–2008) was a Japanese singer-songwriter who specialized in the shamisen.
In 1961, with the support of her father, Kashima Daiji (鹿島大治), a researcher of ryūkōka and historical Japanese music, she established the Momoyama school (桃山流, Momoyama-ryū) of shamisen-playing and became an iemoto.
Two years later, in 1963, Momoyama was introduced to the Miyazono-bushi (宮薗節) style of jōruri and came to be one of the few students of its then-final master Miyazono Senju IV.
In 1974, she retired as iemoto of the Momoyama school and became the last disciple of Tomomichi Soeda [ja], an authority on the enka of the Meiji and Taishō eras.
In 1981, Momoyama began a project attempting to resurrect the Ryōjin Hishō, a collection of songs from the Heian period.
