World of Our Own is the third studio album by Irish boy band Westlife. It was released through Sony BMG on 12 November 2001. It reached number one in the United Kingdom and includes the singles "Queen of My Heart" (which was a double A-side with "When You're Looking Like That"), "World of Our Own" (which was a double A-side with "Angel"), "Bop Bop Baby", and the final single from the group's last album, "Uptown Girl". "Evergreen" was later covered by Will Young as his winner's single for the 2002 Pop Idol competition.

The album went 4x Platinum in the UK and is currently the fourteenth biggest selling boy band album ever in the UK. In January 2005, the album was re-released in a 2-in-1 box set with the group's previous album, Coast to Coast.
