"Flatliner" is a song co-written by American country music artist Cole Swindell featuring vocals from Dierks Bentley.

"[1] Joseph Hudak of Rolling Stone gave a negative review of "Flatliner", criticizing it as "a hit that employs the laziest clichés of contemporary country music".

He called the song "a step back for Swindell as a serious artist", compared to the maturity in the lyrics of previous releases "You Should Be Here" and "Middle of a Memory".

[1] In 2017, Billboard contributor Chuck Dauphin put "Flatliner" at number ten on his top 10 list of Swindell's best songs.

[4] Flatliner first entered the Hot Country Songs at number 36 on April 30, 2016 based on 14,000 copies sold when it was released as a preview track before the album You Should Be Here dropped.
