Two Lefts Don't Make a Right...but Three Do is the third full-length album released by Christian rock band Relient K. The album was nominated for a Grammy for Best Rock Gospel Album, but the award that year ended up being won by Worldwide by Audio Adrenaline. This album was initially released with four different covers, each one depicting a separate car wreck. In November 2003, a fifth cover was released, which showed all four cars in a junkyard. That is now the only version of the CD still in print, although a very small amount the four original covers can still be found. It was also released as a combo pack with Deck the Halls, Bruise Your Hand for a few years around Christmas time. The album peaked at No. 38 on the Billboard 200.

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.
