The Lau'agae Ridge Quarry is a prehistoric stone quarry on the eastern side of the island of Tutuila in the United States territory of American Samoa. It is located on a ridge above another archaeological site, the prehistoric village of Tulauta. The quarry site was listed on the National Register of Historic Places in 2000.
The site includes a carpet of stone flakes, evidence of rough stonework (creating forms probably finished in Tulauta), signs of habitation, and two tia'ave, oval stone platforms found in abundance on the island.
