Angus McMillan (14 August 1810 – 18 May 1865) was a mass murderer, explorer and pioneer pastoralist in Gippsland, Victoria, Australia.
Arriving in Australia in 1838, he rose swiftly in colonial society.
In retribution for the murder of a fellow pastoralist and for the killing of livestock, he led many of the Gippsland massacres of 1840-1850, which killed or drove away the region's indigenous population.
The Victorian Federal electorate McMillan was named after him, the division was renamed Division of Monash in 2018.
