The Country Gentlemen was a progressive bluegrass band that originated during the 1950s in the area of Washington, D.C., 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 leader.
The classic line-up from 1960 to 1964 consisted of co-founders Charlie Waller on guitar and John Duffey on mandolin, with Eddie Adcock on banjo and Tom Gray on bass. They were inducted into the International Bluegrass Music Hall of Honor in 1996.
