"Sundown" is a song by Canadian folk artist Gordon Lightfoot, from the titular album, released as a single in March 1974.

1 in Canada on RPM's national singles chart.

The lyrics describe a troubled romantic relationship (often cited as Cathy Smith), with the narrator recounting an affair with a "hard-loving woman [who's] got me feeling mean".

In a 2008 interview, Lightfoot said: I think my girlfriend was out with her friends one night at a bar while I was at home writing songs.
