Five Score and Seven Years Ago is the fifth studio album by Christian rock band Relient K. It was released on March 6, 2007, and is the first full-length album by the band to feature bassist John Warne and guitarist Jon Schneck.

Relient K is an American rock band formed in 1998 in Canton, Ohio, by Matt Thiessen, Matt Hoopes, and Brian Pittman during their third year in high school and time at Malone University. The band is named after guitarist Hoopes' automobile, a Plymouth Reliant K car, with the spelling intentionally altered to avoid trademark infringement over the Reliant name.
