"One Hell of an Amen" is a song co-written and recorded by American country rock artist Brantley Gilbert. It was released in November 2014 as the third single from his third studio album Just as I Am.

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. The song is about the loss of loved ones, using "a fallen soldier and a cancer victim" as examples.

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. 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. His heart is totally in the right place. But the execution is absolutely horrendous. 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." and "His monotonous delivery doesn’t help matters, but the song was beyond saving anyway."

The music video was directed by Shane Drake and premiered in January 2015.

The song reached No. 1 on the Country Airplay chart in its 37th week of release (chart dated August 8, 2015). It is his fourth No. 1 on the chart. The song has sold 428,000 copies in the US as of September 2015.
