Johann Adolph Hasse (baptised 25 March 1699 in Bergedorf, Germany – 16 December 1783 in Venice) was an 18th-century German composer, singer and teacher of music. Immensely popular in his time, Hasse was best known for his prolific operatic output, though he also composed a considerable quantity of sacred music. Married to soprano Faustina Bordoni and a great friend of librettist Pietro Metastasio, whose libretti he frequently set, Hasse was a pivotal figure in the development of opera seria and 18th-century music.
Hasse was born in Bergedorf, near Hamburg.
