"Don't Worry Baby" is a song by American rock band the Beach Boys from their March 1964 album Shut Down Volume 2. Written by Brian Wilson and Roger Christian, Wilson's lead vocal on the track is considered one of his defining performances, and he later referred to "Don't Worry Baby" as perhaps the Beach Boys' finest record. It was issued in May 1964 as the B-side of "I Get Around", and charted separately at number 24.

Shut Down Volume 2 is the fifth album by the American rock band the Beach Boys, released March 2, 1964 on Capitol Records. Produced by Brian Wilson, it is the follow-up to the band's Little Deuce Coupe, released the previous October, and to Shut Down, a Capitol compilation album. Shut Down Volume 2 was the first of three studio albums that the band released in 1964, and the first recorded without guitarist David Marks, who departed from the band following disagreements with manager Murry Wilson. The album reached number 13 in the US during a chart stay of 38 weeks.
