"The Heart Won't Lie" is a song written by Kim Carnes and Donna Terry Weiss, and recorded as a duet between American country music artists Reba McEntire and Vince Gill. It was released in February 1993 as the second single from Reba's album It's Your Call. The song reached the top of the Billboard Hot Country Singles & Tracks (now Hot Country Songs) chart.

"The Heart Won't Lie" as told by Reba: "Originally Kenny Rogers and I were looking at doing this song as a duet but we could never get it to sound just right because of the different ranges of our voices. Unfortunately, it just didn't work out. Later when I was working on a new CD, I remembered that song and called Kenny to see if he was recording it and if not, could I have it and he passed it along to me. We asked Vince Gill to sing the background harmonies on the song. Tony Brown, who was co-producing the CD with me, suggested letting Vince do more than just sing harmony on the song, so he took a couple of verses, and we decided to turn it into a duet.

"It worked out well in the end for everyone - except, I think, Vince. He doesn't really care for videos and this one turned into a four-day shoot. It was great to spend time with Vince and get to watch him do what he called his Gomer Pyle imitation for his character. But I had to promise him that if he ever does another song with me, he will never have to suffer through a four-day video shoot again!."

The two performed the song on the 1992 Academy of Country Music Awards.

Reba and Vince performed the song on the TV series Evening Shade playing themselves in the episode "Ava Takes A Shower."

The music video was directed by Jon Small and premiered in early 1993.

The song debuted at number 51 on the Hot Country Singles & Tracks chart dated February 20, 1993. It charted for 20 weeks on that chart, and reached Number One on the chart dated April 10, 1993, where it stayed for two weeks. It was McEntire's seventeenth Number One single, and Gill's third Number One.
