Tony Mortimer (b. 1971) is British songwriter, composer, singer and was member of the 1990s UK chart-topping boy band East 17, with whom he enjoyed seven top-5 singles and no fewer than four hit albums between 1992 and 1997. He turned to songwriting when the group disbanded in 1997 in the wake of fellow member Brian Harvey's controversial comments about Ecstasy.

Since 1997, Tony has attempted to create two new bands, the most significant being Subzero, created with Scottish vocalist Jinky "JJ" Gilmour (ex-The Silencers) and two other friends. An album was recorded and record deals in the works but the members agreed that the project didn't seem to fit and disbanded with Jinky continuing in a mildly successful solo career and Tony continuing to work on solo material which is as yet unreleased.

In 1998, Mortimer's East 17 bandmates briefly reformed the group without him and released two singles as E17. They disbanded again the following year.

Tony has continued to function as a producer since 1997 from his studio in Essex as well as recording his own songs for an album to be released on his official website in January 2006.

Tony has his own page on My Space which he updates on a regular basis with new material and news - www.myspace.com/tonymortimer
