Tony Hadley (born Anthony Patrick Hadley, 2 June 1960, Islington, London) is an English pop singer who fronted the 1980s Pop band Spandau Ballet.

The group disbanded in 1989, after their final studio album, Heart Like a Sky, failed to live up to the critical and commercial success of their earlier albums, such as True and Parade. As a matter of fact, Heart Like a Sky was not even released in the United States. In April 1999, Hadley along with fellow band members Steve Norman and John Keeble failed in their attempt to sue Gary Kemp for a share of his royalties, as the band's principal songwriter (recently, however, Norman is again on good terms with Gary and his brother, Martin Kemp, who used to play guitar in the band, which makes a possible reunion less difficult).

After Spandau Ballet disbanded, Hadley pursued a solo career, with considerably less success, signing to EMI and recording his first album, The State of Play, in 1992. After leaving EMI, Hadley formed his own record company, SlipStream Records, and his first release was to be the single "Build Me Up", from the film "When Saturday Comes". Shortly after that, in December 1996, Hadley embarked on an orchestral tour of Europe, along with Joe Cocker, Paul Michiels, Dani Klein and Guo Yue, playing to 500,000 people in six weeks.

On his return from that tour, Hadley signed a joint deal with PolyGram TV, and released his next eponymous solo album, Tony Hadley, in 1997, which included covers and songs that were chosen to match his voice. The album also featured some of his own self-penned songs, such as "She", the song that Hadley wrote for his daughter, Toni. He is the father of four children: Thomas, Toni, and Mackenzie by his wife, Leonie, and Zara (born 21 December 2006) by his current girlfriend, Alison Evers. Hadley split from Leonie in 2003, after twenty years of marriage.
