Johann Wolfgang Franck (17 June 1644 in Unterschwaningen, Mittelfranken – ca. 1710 in London) was a German baroque composer.
He worked from 1673 to 1679 as Kapellmeister in Ansbach and then lived from 1679 to 1690 in Hamburg. Here he initially composed several geistliche Sing-Spiele for the Oper am Gänsemarkt. From 1682 to 1685 he held the position of cantor in St. Mary's Cathedral. From 1690 he lived in London. Together with Robert King, he went there first as a concert promoter (1690 to 1693) and was thereafter only active as composer. Besides operas, he produced some songs (especially for the Concerts in London), cantatas and numerous hymn tunes.
