"Let There Be Love" is a song by the English rock band Oasis from their sixth studio album, Don't Believe the Truth. Written by Noel Gallagher, it is the third Oasis song to feature Liam and Noel on lead vocals, the first being the B-side "Acquiesce", and the second being "Put Yer Money Where Yer Mouth Is". It was released on 28 November 2005 as the third single from the album in the UK (see 2005 in British music), and the second single in the US. It reached number two in the UK charts, capping a very successful year for the band. Many critics cited this song as proof that Oasis had returned to the form seen in the mid-1990s.

A demo for the track was recorded during demo sessions for Standing on the Shoulder of Giants. A bootleg of these demo sessions was leaked onto the Internet in early 2000. This track was given the unofficial title "It's a Crime" on many bootlegs as the track was unknown and unreferenced anywhere before then. The album version of the song is structurally almost exactly the same as the demo with a slight change in melody in the part that Noel sings. The lyrics to the chorus remains intact, but the verses and bridge have totally rewritten lyrics.

The single version of the song omits the second verse and chorus.

A second, Noel-sung demo was released on the "Let There Be Love" DVD single. It has the same lyrics as the album version, and in fact the album version takes some elements from the demo such as the piano. It was probably recorded sometime in 2003 or 2004, prior to the main Don't Believe the Truth recording sessions.

The video is a montage of some of Oasis' live shows during the summer of 2005 including clips of the gigs at Hampden Park and the City of Manchester Stadium. The clips do not actually show the band playing 'Let There Be Love', as the band didn't play the song at either of these gigs. And later, the video clip was appeared on their Don't Believe the Truth tour rockumentary, Lord Don't Slow Me Down.
