Johann Wilhelm Hertel (9 October 1727 – 14 June 1789) was a German composer, harpsichord and violin player.
At an early age Johann Wilhelm accompanied his father, an accomplished viola da gamba player, on tour at the harpsichord.
After further music studies in Zerbst and Berlin, Hertel moved to the Duchy of Mecklenburg-Schwerin, where he made a successful career, initially as principal and later becoming court composer, and likewise undertaking teaching.
During the reign of Duke Christian Ludwig II, Hertel wrote primarily representative instrumental music, while during the reign of his successor, Frederick II (called 'the pious') he focused on sacred music.
Hertel wrote a great number of symphonies, solo concertos, harpsichord sonatas, songs, hymns, cantatas, and oratorios.
