"Little Deuce Coupe" is a song written by Brian Wilson and Roger Christian. The song first appeared as the B-side to The Beach Boys' 1963 single "Surfer Girl". The car referred to is the 1932 Ford Model 18 (deuce being for the year). "Little Deuce Coupe" became The Beach Boys' highest charting B-side, peaking on September 28, 1963, at No. 15 on the Billboard Hot 100.

The music was written by Brian Wilson, with lyrics by local radio station DJ Roger Christian. Its main melody is a twelve-bar blues. The song typified the Beach Boys' car songs, which, along with surfing, glamorized the teenage 1960s Californian lifestyle, later known as the California Myth. It was released on the Surfer Girl album and then again as the title track of the album Little Deuce Coupe. A Christmas-themed spin-off, "Little Saint Nick", was released by the group as a single later in the year.

The car referred to is the Ford Model 18; the 1932 coupe model was referred to as a "deuce coupe."

I dedicate this to Brian Wilson. I loved and still love all the Beach Boys songs. I grew up in Southern California during the time of the Beach Boys. Wonderful times. Wonderful memories. Thank you for listening. Here is my cover of one of their hits; Little Deuce Coup. RIP Brian.
