"Don't You Know You're Beautiful" is the title of a song written by Chris Lindsey, Aimee Mayo, and Karyn Rochelle, and recorded by American country music artist Kellie Pickler.

The song is a mid-tempo in which the narrator assures other females that they are beautiful just as they are, and has been compared to Martina McBride's 2003 single "This One's for the Girls" (which also contains the line "you're beautiful the way you are" and was also co-written by Aimee Mayo).
