"Bo Diddley" is a rhythm and blues and rock and roll song first recorded by Bo Diddley at Universal Recording Corporation in Chicago and released on the Chess Records subsidiary Checker Records in 1955.
Written by Diddley, its lyrics are based on the traditional lullaby titled "Hush Little Baby", and it prominently features the Bo Diddley beat that the singer made famous. It became an immediate hit single that stayed on the R&B charts for a total of 18 weeks, 2 of those weeks at No. 1, and seven more weeks than its flipside (the B-side, "I'm a Man").
It was the first recording to introduce African rhythms into rock and roll directly by using the patted juba beat. It was Diddley's first recording and his first hit single.
The song is featured on many of Diddley's compilation albums including His Best.
In 2012 the A and B-side pair were added to the Library of Congress's National Recording Registry list of "culturally, historically, or aesthetically important" American sound recordings.
In 2017, the single was inducted in to the Blues Hall of Fame.
