"Oh My Darling, Clementine" is an American western folk ballad in trochaic meter usually credited to Percy Montrose (1884), although it is sometimes credited to Barker Bradford. The song is believed to have been based on another song called "Down by the River Liv'd a Maiden" by H. S. Thompson (1863). This American folk song is commonly performed in the key of F Major. Members of the Western Writers of America chose it as one of the Top 100 Western songs of all time.
