Chemistry: The Tour was the second concert tour by British all-female pop group Girls Aloud. It supported their third studio album, Chemistry. Following the success of 2005's What Will the Neighbours Say...? Tour, Girls Aloud performed in arenas across the United Kingdom for the first time. Girls Aloud announced tour dates in October 2005. They performed just ten dates, making it their shortest tour. The tour began in Nottingham on 22 May 2006 and concluded in London on 3 June 2006.
The show was divided into five sections with distinct costumes, including the encore. The set list featured songs mostly from Chemistry, but also included singles from Girls Aloud's first two albums and cover versions. Girls Aloud began the show by rising from underneath the stage to perform the opening number "Biology". The stage included video screens and a catwalk which extended into the audience.
Chemistry: The Tour received generally positive reviews from contemporary music critics who praised Girls Aloud's energy and fun. The tour was a commercial success, leading to the announcement of another arena tour the following year. A recording of the show was released on DVD in November 2006, oddly titled Girls Aloud: Greatest Hits Live From Wembley Arena to coincide with the release of the group's first greatest hits collection The Sound of Girls Aloud: The Greatest Hits.
