Diamond in the Rough is the fourth studio album released by American country music artist Jessi Colter. It was the second album issued by Colter in 1976; the previous was Jessi, released earlier in the year. Diamond in the Rough was issued under Capitol Records and was produced by Ken Mansfield.
Diamond in the Rough was issued as Colter's second studio album in 1976, containing ten new tracks, which included a cover of The Beatles's "Hey Jude". The album only spawned one single released in 1977, titled "I Thought I Heard You Calling My Name", which peaked at #29 on the Hot Country Songs chart. The song's B-side, "You Hung the Moon (Didn't You Waylon)", was also released as a single, however it failed to chart. Diamond in the Rough peaked at #4 on the Top Country Albums chart (Colter's third album in a row to do so), while also reaching #79 on the Billboard 200 albums chart. The album was co-produced by Colter's husband, country music artist Waylon Jennings, who also produced her previous two albums.
