"I Was Jack (You Were Diane)" is a song recorded by American country music singer Jake Owen.

It was written by David Ray, Tommy Cecil, Jody Stevens, Craig Wiseman, and John Mellencamp, with production handled by Joey Moi.

It is Owen's first single from his sixth studio album Greetings from... Jake.

Rolling Stone writer Chris Parton described the song: "Owen's updated version highlights the original's impact on present-day America, while a regular Joe reminisces about falling in love to the tune years before.

Owen said that he wanted to record it because of the feelings of nostalgia that the lyrics evoked in him.
