"Thinking 'Bout You" is a song written by American country music singer Dustin Lynch with Andy Albert, Hunter Phelps, and Will Weatherly. It was first recorded by Lynch as a duet with fellow American country singer Lauren Alaina for Lynch's fourth studio album, Tullahoma (2020). Due to promotional conflicts, the song was re-recorded in 2021 featuring Canadian country singer MacKenzie Porter for release as the album's fifth single. The single version with Porter debuted to American country radio on May 3, 2021.
The latter version of the song was also included on Lynch's 2022 album Blue in the Sky as its lead single.
