The Rosenstock Village site is a historic site located in Frederick County, Maryland, United States, near the city of Frederick.

It is similar to the Montgomery Complex, which is a cultural complex made up of Late Woodland sites located on the Potomac River. The site was excavated in 1979 and from 1990 to 1992, and estimates suggest that 93% of the site remains undisturbed.
