Jean-Baptiste Capronnier (1 February 1814 – 31 July 1891) was a Belgian stained glass painter. Born in Brussels, Belgium in 1814, he had much to do with the modern revival of glass-painting, and first made his reputation by his study of the old methods of workmanship, and his clever restorations of old examples, and copies made for the Brussels archaeological museum. He carried out windows for various churches in Brussels (including the Église Royale Sainte-Marie), Bruges, Amsterdam and elsewhere, and his work was commissioned also for France, Italy and England. At the Paris Exhibition of 1855 he won the only medal given for glasspainting. He died in Schaerbeek in 1891.
