The Buenavista Protected Landscape is a conservation area and an archaeological site located on Bondoc Peninsula in the southern Luzon province of Quezon in the Philippines.

It conserves an important watershed area composed of secondary-growth forest, grassland and coconut land in the rural village of Buenavista within the coastal municipality of Mulanay.

According to the National Museum of the Philippines, the limestone coffins are "similar to ancient sarcophagus with round holes where wooden posts of houses or sheds may have stood" but the covers are missing, probably due to irresponsible treasure hunters during the Yamashita hype in the late 20th century.

In addition, archaeologists have also discovered shards of earthen jars, metal objects, and bone fragments of humans, monkeys, wild pigs, and other animals in the tombs.
