The Adams County Paleo-Indian District is an archaeological site near Sandy Springs in Green Township, Adams County, Ohio, United States.

Approximately 10,000 years BP, the site was repeatedly occupied by groups of Paleo-Indians, who took advantage of its location near salt springs to hunt local wildlife. Artifacts found at the site are concentrated in multiple small middens that are believed to represent individual campsites. Among these artifacts are gravers, scrapers, and projectile points.

Within a few years of the site's discovery, a 1982 report noted that it had yielded more than seventy fluted points  (elsewhere identified as Clovis points), which the report's authors declared made it an example of "unusual size and complexity".  Other researchers have designated them as Gainey Points. Such large sites as Adams County, or "Sandy Springs" as it is also known, are rare among Paleo-Indian sites; most discoveries related to the people are isolated finds,  although a comparable archaeological district known as the Welling site has been discovered in Coshocton County, Ohio. It appears that southern Adams County was highly significant for such primitive peoples because of its geology  one of Ohio's few regions with combined shale and limestone bedrock, the Sandy Springs area is geologically similar to the Kentucky Bluegrass, making it a natural migration route for herds of animals roaming the Bluegrass.  As a result, Paleo-Indian hunters learned to use the area to watch for and ambush large herds of animals, which would have been traveling slowly due to the large river.
