"One Hell of an Amen" is a song co-written and recorded by American country rock singer Brantley Gilbert.

Gilbert revealed that the song is based on a true story regarding the death of a US military soldier who was like a brother to one of his close friends.

[2] Giving it a B+, Bob Paxman of Country Weekly wrote that "Brantley's low-key, heartfelt delivery, along with straightforward lyrics that aren't trying to make a statement, dispel any notion of pandering", although he criticized the "crunchy and overloaded" production.

[2] A less favorable review came from Kevin John Coyne of Country Universe, who rated the song a "D" criticizing the weak songwriting as well as the lack of emotion in Gilbert's vocals, writing that "I actually feel kind of bad for Brantley Gilbert.

Attempting to tackle two different tragedies in one song – a fallen soldier and death by cancer – and fails to stumble upon any truth in either individual situation, let alone a compelling connection between the two."
