The Foggy Mountain Boys was an American bluegrass band. The band was founded by guitarist Lester Flatt and banjo player Earl Scruggs and is viewed by music historians as one of the premier bluegrass groups in the history of the genre. The band was originally formed in 1948 by Flatt, who had been a member of Bill Monroe's bluegrass band. Flatt brought Scruggs with him shortly after leaving Monroe.

Flatt and Scruggs and The Foggy Mountain Boys (in various forms and line-ups) recorded and performed together up until 1969. The Foggy Mountain Boys are seen as one of the landmark bands in bluegrass music.

Scruggs is widely considered the most influential player of the bluegrass banjo who ever lived. Playing since the age of five, Scruggs gained his initial spotlight when he played briefly with Bill Monroe, considered by many as the father of bluegrass music. His lightening fast syncopation and virtuosity wove themselves into an innovative three finger picking style that became the standard for mastering the instrument.
