Ambrose Goddard Hesketh Pratt (31 August 1874 – 13 April 1944) was an Australian writer born into a cultivated family in Forbes, New South Wales.

But this life must not have suited him, as he left to follow a more adventurous existence, including work on a Pacific trading steamer and as a Queensland drover.

He travelled to England where he commenced writing novels and stories for magazines such as The Bulletin and The Lone Hand, and began what was to become a career in journalism with the Daily Mail which brought him back to Australia in 1905.

He joined The Age as a journalist in 1905, gaining considerable influence (David Syme was a mentor), and was a member of the party with Prime Minister Andrew Fisher visiting the newly founded Union of South Africa for the opening of its parliament.

Pratt's novels frequently focussed on criminal outsiders such as "The Push" (a Sydney larrikin element analogous to the "bodgies" of the 1950s, "rockers" of the 1960s and "bikies" of today), and bushrangers such as Captain Thunderbolt and Ben Hall.
