"Stuck on You" is a song written and originally recorded by American singer and songwriter Lionel Richie. It was the fourth single released from his second studio album, Can't Slow Down, released in June 1984, by Motown, and achieved chart success, particularly in the US and the UK, where it peaked at number three and number 12, respectively. "Stuck on You" reached number one on the Adult Contemporary chart, Richie's seventh chart topper.
The song marks Lionel Richie's country music debut and the single's cover photo shows Richie wearing a cowboy hat. "Stuck on You" peaked at number 24 on the Country chart.
The song differs from Richie's other compositions, as it displays a country pop influence rather than R&B.
Cash Box described the song as "an airtight and tender ballad with a nearly country twinge."
In 2003, "Stuck on You" was covered by American group 3T. It was the first single from their second studio album Identity, on which the song also appears in a remixed version called the "Smooth Mix" (also available on the CD maxi). Released in summer 2003, it achieved success in the Netherlands, Belgium and France, where it was a top ten hit.
