"You Don't Know" is a song by American band Berlin, which was released in 1986 as the third single from their fourth studio album Count Three & Pray. It was written by John Crawford and produced by Andy Richards, Bob Ezrin and Berlin. It reached No. 39 in the UK and No. 16 in Belgium.

"You Don't Know" was recorded in London. Recalling the initial recording of Count Three & Pray, Nunn said in a 2014 interview for Pop Entertainment: "It was so bad with this guy in England that we trashed the whole thing. I think we kept one song, "You Don't Know," that he had done. We started all over with Bob Ezrin."

A music video was filmed to promote the single, which gained breakout rotation on MTV.
