The so-called Battle of Pinjarra or Massacre of Pinjarra was an attack that occurred at Pinjarra, Western Australia on a group of up to 80 Australian Aborigines by a detachment of 25 soldiers, police and settlers led by Governor James Stirling in 1834. After attacks on the displaced Swan River Whadjuk people and depredations on settlers by a group of the Binjareb people led by Calyute had, according to white settlers, reached unacceptable levels, culminating in the payback killing of an ex-soldier, Stirling led his force after the party. Arriving at their camp, five members of the pursuit party were sent into the camp to arrest the suspects and the Aborigines resisted. In the ensuing "battle", Stirling reported 15 killed (eleven names were collected later from Aboriginal sources); police superintendent T.T. Ellis later died of wounds and a soldier was wounded. Stirling warned the tribe against payback killings and arranged a peace between the warring tribes, but Calyute continued to break it in raiding the Whadjuk until his demise.
