Thomas Denny (born 1956) is a contemporary British painter and stained glass artist.
Tom Denny was educated at King Alfred's School, Hampstead, and trained at the Edinburgh College of Art and now lives and works in Gloucestershire. He has exhibited extensively and has had numerous commissions both as a painter and a skilled practitioner of stained glass.
His windows are noted for the distinctive way in which light and colour move across the surface. He achieves this effect by acid etching and silver staining each small piece of glass.
He has been responsible for some 60 stained glass commissions for churches and cathedrals, including the Traherne windows at Hereford Cathedral (2007), the Transfiguration window at Durham Cathedral (2010), and the Wisdom window at St Catharine's College, Cambridge (2012). In 2016 two windows inspired by the life of Richard III were installed in Leicester Cathedral. The windows, which cost £75,000, are sited near the king's tomb in the cathedral.
