Ladies of the Canyon is the third studio album by the Canadian singer-songwriter Joni Mitchell, released on Reprise Records in 1970. It peaked at No. 27 on the Billboard 200, and has been certified platinum by the RIAA. The title makes reference to Laurel Canyon, a center of popular music culture in Los Angeles during the 1960s, where Mitchell lived while she was writing the album. Specifically, Mitchell lived and wrote at 8217 Lookout Mountain Avenue, the house which is the subject of Graham Nash's "Our House".
