Breaker Morant: A Play in Two Acts is an Australian play written by Kenneth G. Ross, centred on the court-martial and the last days of Lieutenant Harry "Breaker" Morant (1864–1902) of the Bushveldt Carbineers (BVC), that was first performed at the Athenaeum Theatre, in Melbourne, Victoria, Australia, on Thursday, 2 February 1978, by the Melbourne Theatre Company.

The 1902 court-martial of Breaker Morant was a war crimes prosecution that brought to trial six officers – Lieutenants Harry "Breaker" Morant, Peter Handcock, George Witton, Henry Picton, Captain Alfred Taylor and Major Robert Lenehan – of the Bushveldt Carbineers (BVC), an irregular regiment of mounted rifles during the Second Boer War.
