"Lady Lynda" is a song written by vocalist/guitarist Al Jardine and touring keyboardist Ron Altbach for American rock band the Beach Boys. It was released on the band's 1979 album L.A. (Light Album). Its melody is based on "Jesu, Joy of Man's Desiring" by J. S. Bach. The opening harpsichord is played by Sterling Smith. The lyrics to the song refer to Jardine's then-wife, Lynda Jardine. After the two divorced, the song was rewritten as "Lady Liberty", a tribute to the Statue of Liberty.
