You're Thirteen, You're Beautiful, and You're Mine is a live EP by Australian pub rock band Cold Chisel, recorded at the Regent Theatre in Sydney in October 1978 and released in November 1978.

After a long period of unavailability, the EP was re-released as a bonus disc with the second pressing of the compilation album Chisel (1991).

Walker later said the title was "dreamed up at a drunken recording session, and obviously ten thousand other people thought it was funny too.

According to his memoir, Working Class Man, Cold Chisel played "God Save The Queen" (Australia's national anthem in 1978) as their opening song at this concert, jokingly intended to compel the entire audience to stand up.
