"I Could Sing of Your Love Forever" is a popular Christian rock and worship song by the English contemporary Christian band Delirious?. The song's popularity has reached far beyond the band's; CCLI places the song among the 30 most-sung worship songs in the United States and has been called a "modern worship classic". According to Martin Smith, the author of the song:

Delirious? have released it several times in different forms. It was first recorded as the last track on Cutting Edge 2; in this incarnation, it was a six-minute soft pop song featuring extensive use of eBow and choir. Later, it was re-recorded for Deeper, the band's "d:finitive worship collection"; here, it became a full-blown rock ballad with gospel influences. A radio edit of this version was released as a single (see Single Release, below). A Spanish version of the original, translated as "Cantaré de Tu amor por siempre", appeared on the band's album Libertad.

The song has been covered numerous times, with variations in style and performance, particularly within the CCM genre. The most popular of these covers (most notably within the US) was by worship group Sonicflood. The song, which appears on their self-titled debut album, is a duet with Lisa Kimmey from R&B outfit Out of Eden. Alternately, the cross-over group Switchfoot (made up of Christian members) has also sung this song during various concerts. Christian singer tobyMac has also covered part of this song live after his hit, Lose My Soul. It has also been covered by Christian/Rock band, The Lads, in their Alive in Concert album in 2003. Canadian pop singer Justin Bieber covered this song on a live feed on his Instagram on the 16th of May 2017.
