Timothy James Arthur Wheeler (born 4 January 1977) is an Irish singer, songwriter and musician from Northern Ireland.

He has written nearly all of Ash's notable works, such as "Oh Yeah", "Shining Light", "Girl from Mars", "Kung Fu", and "Goldfinger".

[10] As part of Channel 4's program The JD Set, Wheeler worked with Emmy The Great, The Crookes, And So I Watch You From Afar, and Ma Mentor, joining each band in covering songs by Pixies, and then performing at London's XOYO on 24 March 2011.

[11] Wheeler has also been involved with film and TV soundtrack work, most notably Ashes (2012), Fleming: The Man Who Would Be Bond (2014)[12] and the Shaun the Sheep Movie (2015).

[17] In September 2014, Wheeler announced the release of his first solo album, Lost Domain, a heartfelt and emotional response to the loss of his father George to dementia.

Lost Domain was released on Sony Red on 3 November 2014, with a portion of the proceeds being donated to The Alzheimer's Society, a charity Wheeler has worked closely with since his father's death in 2011.

[1] Lost Domain is an album in which Wheeler battles to come to terms with his loss, charting his father's rapid decline into illness, his death and the tumultuous effect that it had on his life over the course of 11 songs.

He also plays a Gibson SG and Gretsch Silver Jet, which was frequently used both live and in the studio since Ash's album Twilight of the Innocents.

He also uses a Gibson Custom Inspired By Kiefer Sutherland Semi-Hollow KS-336 guitar on a number of tracks live, including songs such as "Walking Barefoot".

The Flying V guitar that Wheeler set on fire on the Ash Meltdown tour is now on display at the Oh Yeah centre in Belfast.

[8] With the release of the band's fifth studio record Twilight of the Innocents, in 2007, Wheeler spoke of how if the group hadn't toured so heavily they would have been more prolific, that: "It would have been cool to have twice as many songs by now.
