Friedrich Sustris (c. 1540, in Padua – 1599, in Munich) was an Italian-Dutch painter,^[1] decorator and architect. He was a son of the artist Lambert Sustris, who worked in Italy.

Sustris got his training from his father Lambert in Venice and Padua.^[2] From 1563 to 1567 he was trained by Giorgio Vasari in Florence, after he had returned from a stay in Rome in 1560. His first patron was Hans Fugger who ordered the decoration of the Fugger mansion in Venice. He was the son-in-law of Jan Kraeck.^[2] From 1573 onwards Sustris worked for William V, Duke of Bavaria^[1] in Landshut before he became chief architect to the Bavarian court with William's accession to the throne in 1579.
