The Backusburg Mounds (15-CW-64)[1] are an archaeological site in the Jackson Purchase region of the U.S. state of Kentucky.

Located near the tiny community of Backusburg in northwestern Calloway County, the mounds are one of the region's premier archaeological sites.

As late as the 1930s, this largest mound had never been plowed; it lay in dense woodland, and among the trees growing upon it were some of considerable size.

Such findings are not unprecedented in the area; a field close to Backusburg has long produced skeletons, projectile points, and pottery when plowed, leading to its identification as a former village site.

[1] Additional work was finally conducted at Backusburg in mid-2013, as another team of Murray State archaeology students was assigned to document the site more carefully for their field school.
