"As Long as You Love Me" is the second single by the Backstreet Boys from their debut album in the United States and the second single from Backstreet's Back internationally. It was released in September 1997 internationally and in October of the same year in the United States. It is one of the bands' largest hits and considered one of their signature songs. It peaked at #1 in New Zealand and the Philippines, #2 in Australia and Austria, #3 in the United Kingdom, #4 in Switzerland and Sweden, and #5 in the Netherlands and Norway. At The 1997 MTV Europe Music Awards the song won Select Video. The radio version of the song was featured on the 1998 compilation album Now That's What I Call Music! As well as their three compilation albums: The Hits - Chapter One (2001), Playlist: The Very Best of Backstreet Boys (2010), and The Essential Backstreet Boys (2013).

The song is their biggest selling single in the UK and the 13th biggest selling boyband single of the 1990s in the UK selling 430,000 copies. In the US, although it was never released as a commercial single, it became an MTV staple and a radio airplay hit, spending 56 weeks on the Billboard Hot 100 Airplay chart, with a peak of #4. It's about a man professing his love for a woman. In the song, he tells her he doesn't care about her shady past, as long as she loves him back. The song was a last minute addition to the album, as Clive Calder, then-chairman of Zomba, heard the song and called Jive Records president Barry Weiss, who then contacted the band's manager, Johnny Wright.
