Did Banjo Paterson write The Dying Stockman?

No. The reason for the confusion is most likely that The Dying Stockman was included in a collection of Bush Ballads, "The Old Bush Songs", published by AB 'Banjo' Paterson in 1905.

There are a number of different theories regarding the origin and history of this Australian song. They include the following possibilities:

• It is a traditional song based on "The Old Stable Jacket", a British folk song
• Australian Country Music singer Slim Dusty "borrowed" the song but it is based on a traditional song.
• Dying Stockman had additional lyrics written by Slim Dusty.
• Some sources suggest it was written by a Victorian pastoralist by the name of Horace Flower, but the style of music is more suited to a later time than Flower lived.
