The Aoki Site (青木遺跡, Aoki iseki) is an archaeological site with the traces of a late-Yayoi period (3rd century) to early-Nara period (6th century) settlement located in the Nagae neighborhood of the city of Yonago, Tottori Prefecture, in the San'in region of Japan.

It is located on the Aoki Hills at the northern end of the "Chojabaru Plateau", on the left bank of the Hino River.

The area has long been known to be the location of many ancient burial mounds but came to academic notice only in 1971 when rescue archaeology prior to development of the site into a public residential housing complex found approximately 130 pit dwelling sites and 240 pillar-supported building foundations, many remains of burial mounds, square grooved tombs, underground storage pits.

In addition, tens of thousands of artifacts such as Yayoi pottery, metalware, stone tools, jade magatama and other beads, and other daily utensils, as well as grave goods, were unearthed over a 40 hectare area.

The large amount of earthenware enabled a detailed chronological evaluation of the site.
