Johann Stobäus (6 July 158011 September 1646) was a composer and lutenist.
Stobäus was born at Graudenz (now Grudziàdz, Poland) in the PolishâÂÂLithuanian Commonwealth. From 1599 to 1608 he was a pupil of Johannes Eccard, the Kapellmeister of Königsberg (in the Duchy of Prussia, a vassal duchy of Poland). In 1601 he joined the princely Kapelle as a bass singer, and in 1602 he became Kantor at Königsberg Cathedral. In 1626 he succeeded Eccard as Kapellmeister, remaining in the post until his death. He died at Königsberg.
Stobäus, known as Stobaeus Grudentinus Borussus for his birthplace, wrote music for liturgical use, as well as songs and compositions for lute. Much of his manuscript music was lost in World War II; what remains is largely held at the Berlin State Library. Stobäus's Commonplace Book, containing songs, instrumental music and drawings of instruments, is preserved at the British Library (Sloane MS 1021).
