"The Ballad of Jed Clampett" was the theme song for The Beverly Hillbillies TV show and movie, providing the back story for the series. The song was written and composed by Paul Henning, and sung by Jerry Scoggins, who was accompanied by bluegrass musicians Lester Flatt and Earl Scruggs. When the theme was released as a single, Flatt sang lead vocals instead.

The single version, released to radio and retail sale, merged both the opening and closing lyrics of the theme song from the television series. The first two verses (starting with "Come and listen to a story about a man named Jed" and "Well the first thing you know, old Jed's a millionaire") comprised the opening theme, while the closing theme ("Now it's time to say goodbye to Jed and all his kin ...") served as the third verse. A banjo-led bridge serves as the fill between verses and as the fade-out coda.

Although the first two seasons of The Beverly Hillbillies lapsed into the public domain, "The Ballad of Jed Clampett" did not and is typically edited out of public-domain releases of these episodes.

The song spent twenty weeks on the Billboard country singles charts, reaching a peak of number one for three weeks and reached #44 on the Billboard Hot 100 in 1962.

During the original run of The Beverly Hillbillies, special lyrics were written and inserted into the opening theme, advertising regular sponsors such as Kellogg's cereals and Winston cigarettes.

"Weird Al" Yankovic merged the first two stanzas of the Ballad with the instrumentals to the Dire Straits song "Money For Nothing" in his 1989 single "Money for Nothing/Beverly Hillbillies*", which was written for his film UHF.

In the late 1970s, Saturday Night Live did a spoof on the "Beverly Hillbillies," in a sketch about a wealthy family from an oil-rich Mideastern country moving to Southern California. The theme song in the sketch was called, "The Bel-Arabs."
