The Link Farm State Archaeological Area (40 HS 6), also known as the Duck River Temple Mounds or Duck River site, is a Mississippian culture archaeological site located at the confluence of the Duck and Buffalo Rivers south of Waverly in Humphreys County, Tennessee.

The site is most widely known for the stone artifacts found during excavations in the late 19th century.

[1][2][3] The site features include two substructure platform mounds, three conical burial mounds, a loaf shaped mound, and a central plaza area measuring 150 metres (490 ft) east to west and 250 metres (820 ft) north to south.

In March 1895 the same but slightly deeper location was also the site of the discovery of a paired male and female set of Mississippian sandstone statues nicknamed "Adam" and "Eve".

The Duck River cache was acquired by the McClung Museum of Natural History and Culture in Knoxville, Tennessee and is now on permanent display.
