The Country Gentlemen were a bluegrass band that originated during the 1950s in the area of Washington, DC, United States, and recorded and toured with various members until the death in 2004 of Charlie Waller, one of the group's founders who in its later years served as the group's "focal point and leader."

"The Classic" line-up of the Country Gentlemen from 1960–64, consisting of co-founders Charlie Waller on guitar and John Duffey on mandolin, with Eddie Adcock on banjo and Tom Gray on bass, were inducted into the International Bluegrass Music Hall of Honor in 1996.
