"God's Gonna Cut You Down" (also known as "God Almighty's Gonna Cut You Down", "God's Gonna Cut 'Em Down", "Run On" and "Sermon") is a traditional American folk song. It was first recorded by the Golden Gate Quartet in 1946 and first issued in 1947 by the Jubalaires. Since then, the track has been recorded in a variety of genres, including country, folk, alternative rock, electronic and black metal. The lyrics warn evildoers that they cannot avoid God's eventual judgment.

As "God's Gonna Cut You Down", it was performed by Odetta on Odetta Sings Ballads and Blues (1956), Johnny Cash on the posthumously released American V: A Hundred Highways (2006). Marilyn Manson also used this title for a non-album single in 2019. As "Run On", it has been recorded by Elvis Presley and Tom Jones, and The Blind Boys of Alabama. The song has been covered by many other artists. A version by Bill Landford & the Landfordaires from 1949 was later sampled heavily for the 1999 song "Run On" by Moby.
