"I Can Only Imagine" (sometimes shortened to "Imagine") is a single recorded by Christian rock band MercyMe. Written and composed by Bart Millard, the song, based around a main piano track, was inspired by the death of Millard's father and considers what it would be like in Heaven and to be standing before God. The song was first issued as a track on MercyMe's 1999 album The Worship Project, which was released on an independent record label. The song was re-recorded and included on their 2001 major-label debut album Almost There as the fifth song on the album.

"I Can Only Imagine" was released in 2001 as the album's lead single. It gained significant airplay on Christian radio formats before crossing over to mainstream radio formats such as adult contemporary and Top 40 in late 2003 and into 2004; to aid in promotion to these markets, a double A-side physical single (combined with "Word of God Speak") was released in 2003. It charted on several formats, including the Billboard Adult Contemporary (where it peaked at No. 5) and the Hot 100 (where it peaked at No. 71). In 2002, "I Can Only Imagine" earned the Dove Awards for 'Pop/Contemporary Recorded Song of the Year' and 'Song of the Year'; Millard earned the Dove Award 'Songwriter of the Year' at the same ceremony. In 2010, the song was certified platinum by the RIAA for sales of over one million digital downloads, and is the first (and so far only) Christian single to reach that milestone.
