Waylon & Willie is a duet album by Waylon Jennings and Willie Nelson, released on RCA Victor in 1978. It was number 1 album on country charts for ten weeks. The record contains three songs sung individually by each of the two artists, as well as five duets. Some of the tracks used on the album had previously been released in some form; these were mostly redone using overdubbing.

The album's biggest hit was "Mamas Don't Let Your Babies Grow Up to Be Cowboys", which hit #1 on the country charts, entered the pop charts and earned the duo a Grammy Award for Best Country Vocal Performance by a Duo or Group. Three other of the album's songs – "Lookin' for a Feeling," "I Can Get Off on You," and "The Wurlitzer Prize (I Don't Want to Get Over You)" – also reached the top of the charts, while "If You Can Touch Her at All" peaked at #5.

The original liner notes, complimenting Jennings and Nelson on their ability to surprise and deliver solid material, were written by Chet Flippo of Rolling Stone. Waylon & Willie was reissued by RCA Records in 2001. The 2001 CD marks the first time the full album was issued on CD in the United States; previous US CD issues contained only eight of the album's eleven songs.
