Laili is a limestone cave located near the town of Laleia, Manatuto District, East Timor. Archeological findings in Laili provide evidence that the cave was occupied by modern humans 44,600 years ago, making it the second oldest known habitation in Wallacea aside from Madjedbebe in mainland Northern Australia.

The age of findings made in Laili corroborates the theory that humans spread from Asia to Australia through the Southern route, via Java and the Lesser Sunda Islands.

Findings from the cave provide evidence for occupation spanning 44,600 to 11,200 years before present. Usage of the cave increased towards the end of the Last Glacial Maximum 15,000 years ago, suggesting a dramatic increase of the population as sea levels rose.
