Mat Martin (b. August 19th, 1980) is a British composer, producer, improviser, guitarist, banjoist and player of fretted strings.

Mat works across genres, and is mainly known an an accompanist to singer-songwriters such as Kirsty McGee, Joanna Chapman-Smith, Myshkin and Kreg Viesselman. He also composes and improvises experimental music which has been performed by several international free-improvising musicians. A by-product of his compositional practice are gestural abstract charcoal drawings. His composed work is scored using a combination of traditional western notation and graphics. The visual and sonic style of his experimental work is often quiet, textural and minimal.

Born in Bath, Somerset, Mat is half British and half French. He grew up in Bristol and studied music in London and Devon. He holds a BA in Music Technology from Rose Bruford College (2001) and an MPhil/PhD from Dartington College of Arts (2010), where he studied composition under Edward Cowie and Alexander Goehr. His professional performance career began in 2003 with early session and touring work for Kirsty McGee's "Frost" album. Since then he has performed and recorded with The Brute Chorus, Karine Polwart, Inge Thomson, Joanna Chapman-Smith, Quiet Loner, Guillemots, Boo Hewerdine, Jenny McCormick, Kreg Viesselman, Myshkin's Ruby Warblers, Tim Van Eyken and Truckstop Honeymoon. He has also produced albums for Kirsty McGee, Joanna Chapman-Smith and Quiet Loner. In 2011 McGee's live album, produced by Mat, was awarded Vox Pop for Best Live Album in the 10th Annual Independent Music Awards.
