Martin Cash is a 1955 Australian biography by Frank Clune about the bushranger Martin Cash.
It was also published as Martin Cash: The Lucky Bushranger and Martin Cash: The Last of the Tasmanian Bushrangers.
The Age said "the book bears signs of having been hastily put together. Mr Clune's facile style is a little too facile." However the reviewer thought it was also "very entertaining."
The Sydney Morning Herald review called Clune "Australia's cliche expert" and listed the book's cliches in its review.
