Portrait of Baudouin de Lannoy is a small oil-on panel portrait by the Early Netherlandish painter Jan van Eyck, completed c. 1435. It shows Baldwin of Lannoy, a contemporary Flemish statesman and ambassador for Philip the Good at the court of Henry V of England. From surviving documents it is known that the work was commissioned to mark his entry into the order Baudouin de Lanno. He is in a formal pose, holding a wooden stick in his right hand, and a gold ring on his little finger. Van Eyck's surviving early portraits typically show the sitter holding an emblem of his profession and class.
