Margo Timmins is the lead vocalist of Canadian alternative country and folk rock band Cowboy Junkies. She is the sister of Michael Timmins, the band's lead guitarist, and Peter Timmins, the band's drummer. Her ethereal vocals, paired with the band's spare and low-key instrumentation played at a relaxed pace, lend the band its unique atmospheric sound.

Cowboy Junkies are an alternative country and folk rock band formed in Toronto, Ontario, Canada in 1985 by Alan Anton (bassist), Michael Timmins, Peter Timmins (drummer) and Margo Timmins (vocalist). The three Timminses are siblings, and Anton worked with Michael Timmins during their first couple of bands. John Timmins was a member of the band but left the group before the recording of their debut studio album. The band line-up has never changed since, although they use several guest musicians on many of their studio albums, including multi-instrumentalist Jeff Bird who has performed on every album except the first.
