"Don’t Worry Baby" is a song written by Brian Wilson and Roger Christian, produced by Wilson and first recorded by the Beach Boys. The band's version, a tender ballad with falsetto lead vocal by Brian, was first released on their 1964 album Shut Down Volume 2. It was also released as the B-side of The Beach Boys' first U.S. number-one hit single, "I Get Around", also reaching number 24 on the Billboard Hot 100 in its own right. The single was released in the United States in May 1964 through Capitol Records. It was released a month later, in June 1964, in the United Kingdom.

Brian Wilson cited the song as his attempt to capture the essence of his all-time favorite record, "Be My Baby" by the Ronettes, who would later cover this song. At one time, Wilson listened to his 45 record of the song he "could never do" up to 100 times a day.

John Lennon's 1980 hit, "(Just Like) Starting Over", is considered by some^[who?] to somewhat borrow from the chorus melody of "Don't Worry Baby", while Garbage's 1998 hit, "Push It", contains an interpolation of its chorus.
