Patrick Reyntiens, OBE, (born 1925) is an English stained glass artist, described as the "leading practitioner of stained glass in this country."
Reyntiens was born in London, of Belgian extraction. He was educated at Ampleforth College, Edinburgh College of Art and St Marylebone School of Art. His artistic career was interrupted by military service in the Scots Guards from 1943-1947. He set up an arts educational centre later known as the Reyntiens trust with his artist wife Anne Bruce at Burleighfield House in Loudwater, Buckinghamshire. Smaller church commissions in Buckinghamshire included Christ Church Flackwell Heath, St Mary the Virgin's Church, Fawley, St Mary the Virgin, Turville and St Paul's Bledlow Ridge. Reyntiens then moved to Somerset where he has lived for many years and designed a window for the church of Stoke St Mary. His work is included in the stained glass collection at the Victoria and Albert Museum.
He is notable for his work on Liverpool's Roman Catholic Cathedral and on the new Coventry Cathedral in collaboration with the artist John Piper. He also designed the windows of many other buildings in the United Kingdom, Europe and the United States.
His son John is also a distinguished stained glass artist.
