The What Will the Neighbours Say...? Tour was the first concert tour by British all-female pop group Girls Aloud. It supported their first two studio albums, Sound of the Underground and What Will the Neighbours Say?. Girls Aloud initially planned to tour in 2003 with their fellow Popstars: The Rivals contestants; however, the tour was cancelled due to poor ticket sales. Girls Aloud announced their first headlining tour in December 2004. Girls Aloud performed 22 dates in theatre-sized venues across the United Kingdom and Ireland, beginning in Nottingham on 4 May 2005 and concluding in Dublin on 2 June 2005.
The show, featuring a stairway on the stage, was divided into four distinct sections, including a ballad section. The set list consisted of songs from Girls Aloud's first two albums, as well as cover versions. The tour received generally favourable reviews from critics. The tour was a commercial success, allowing Girls Aloud to perform in arenas for their Chemistry Tour in 2006. In November 2005, the show was released on DVD as What Will the Neighbours Say? Live in Concert.
