"Hangover Tonight" is a song co-written and recorded by American country music artist Gary Allan.

The song was written by Allan, Chris Stapleton, Cary Barlowe, and Jesse Frasure.

"[2] An uncredited review from Taste of Country stated that "Like he did with 'Every Storm (Runs Out of Rain),' Allan returns with a song no one was expecting.

The singer continues to reinvent himself, even if that means going back to what many fans fell in love with a decade ago.

Paired with plenty of electric guitar, organ, throwback wah-wah and Gary's signature gravelly vocal, this tune is dead sexy.
