Josse Lieferinxe (fl. c. 1493–1503/08) was a South Netherlandish painter, formerly known by the pseudonym the Master of St. Sebastian. Originating in the diocese of Cambrai in Hainaut, then part of the territories ruled by the Dukes of Burgundy, Josse Lieferinxe was documented as a "Picard" in the regions of Avignon and Marseille at the end of the fifteenth and in the early sixteenth centuries. He was first mentioned in Provence in 1493.
