The Warrowen massacre was an apparent mass killing of Bunurong people by a group of Kurnai people in the vicinity of present-day Brighton, Victoria, Australia. It is dated to the early 1830s, close in time to the founding of Melbourne. The killing was recorded separately several years later by William Thomas and George Augustus Robinson, based on testimony from Aboriginal sources. Thomas stated that at least 60 people had been killed. According to Robinson, the massacre contributed to the end of an entire Bunurong clan, the Yowengerre, allowing a Kurnai clan to take over their territory.

The Boonwurrung, also spelt Bunurong or Bun wurrung, are an Aboriginal people of the Kulin nation, who are the traditional owners of the land from the Werribee River to Wilsons Promontory in the Australian state of Victoria. Their territory includes part of what is now the city and suburbs of Melbourne. They were called the Western Port or Port Philip tribe by the early settlers, and were in alliance with other tribes in the Kulin nation, having particularly strong ties to the Wurundjeri people.
