Brigadier Maurice "Bunny" Austin, DSO, OBE (15 December 1916 – 13 October 1985) was an Australian Army officer.
He served in the Second Australian Imperial Force in the Second World War, commanded the 2nd Battalion, Royal Australian Regiment in 1952, and led the 1st Battalion, Royal Australian Regiment in the Korean War in 1952–53.
His appointments included Commandant of the Jungle Training Centre; Commander of the Logistic Support Force; Director of Personnel Services and honorary ADC to the Governor General.
The nickname "Bunny" comes from the fact that Thomas Austin (no relation) is believed to have been the first person to introduce rabbits in Australia.
