Paul Sartorius (* christened November 16, 1569 in Nuremberg; † February 28, 1609 in Innsbruck) was a German composer and organist of the late Renaissance and early Baroque periods. Sartorius studied first under Leonhard Lechner in the Latin School of St. Lawrence in Nuremberg and then composition in Italy, probably under Ruggiero Giovannelli in Rome. From 1594, he worked as organist of the court orchestra of the Grand Master of the Teutonic Order Maximilian III in Mergentheim and after his appointment as governor of Tyrol in Innsbruck in 1602.
Sartorius' works are strongly influenced by the Italian style of his time, especially Palestrina's. He composed the ''Missae tres octonis voci Decantandae'' (Munich 1599, 1600), ''Madrigali a cinque vocis'' (Venice 1600), ''Sonetti spirituali a sei voci'' (Nuremberg 1601), the ''Neue Deutsche Liedlein mit vier Stimmen nach Art der Welschen Canzonette'' (Nuremberg 1601), ''Sacrae cantiones sive motecta'' (Venice 1602), additional masses and motets, eight Magnificats and two German songs.
