"Mysterious Girl" is the second overall single and third British single from singer-songwriter Peter Andre's second studio album, Natural (1996).
"Mysterious Girl" was written by Glen Goldsmith, Philip Jackson, Ollie Jacobs and Andre, and produced by Jacobs. The song features guest vocals from Caribbean rapper Bubbler Ranx. It was first released as a single by Melodian Records in Australia on 14 August 1995 but was not released in the United Kingdom until 1996 due to problems regarding the administration of Andre's UK record label, Mushroom Records.
During its original release, "Mysterious Girl" peaked at number one in New Zealand and number two in the Netherlands and the United Kingdom. It was also a top-ten hit in Australia, Austria, Belgium, Denmark, Germany, Hungary, Ireland, Sweden, and Switzerland. On the Eurochart Hot 100, the single reached number 11 in September 1996.
In 2004, the song was re-released in the British Isles and topped the UK Singles Chart following extensive promotion.
