“Young Girl” is a 1968 single by Gary Puckett & The Union Gap, written, composed, and produced by Jerry Fuller. It achieved RIAA million-selling Gold certification. “Young Girl” was one of the band’s top-ten singles in the US, reaching number two on the Billboard 100.

Contrary to its upbeat melody, the song serves as a cautionary tale. Puckett clarified in a Rolling Stone interview that it warns young men against pursuing relationships with underage girls, drawing from personal observations. The lyrics depict the internal struggle of a man attracted to a girl who is too young for a romantic relationship. They express the conflict between his feelings and the societal taboo of such a relationship.
