The six String Quartets, Op. 76 by Joseph Haydn were composed in 1796 or 1797 and dedicated to the Hungarian count Joseph Georg von Erdödy (1754–1824). They form the last complete set of string quartets that Haydn composed. At the time of the commission, Haydn was employed at the court of Prince Nicolaus Esterházy II and was composing the oratorio The Creation as well as Princess Maria Hermenegild Esterházy's annual mass.
