"The Ballad Of The Green Berets" is a patriotic song in the ballad style about the Green Berets, an elite special force in the U.S. Army. It is one of the very few songs of the 1960s to cast the military in a positive light and yet it became a major hit, reaching number one on the Billboard Charts for five weeks in 1966. It was also a multi-market smash, reaching #1 on Billboard's Easy Listening chart, and #2 on Billboard's Country survey.

The song was written by Robin Moore and Staff Sgt. Barry Sadler, while the latter was recuperating from a leg wound suffered as a medic in the Vietnam War. Moore also wrote a non-fiction book, The Green Berets, about the force.

The recording of the song was the number one hit in the United States for five weeks in 1966 and was the number twenty-one song of 1960s, despite the later unpopularity of the Vietnam War. Refer to United States Army Special Forces in popular culture
