Alessandro Striggio (c. 1536/1537 – 29 February 1592) was an Italian composer, instrumentalist and diplomat of the Renaissance. He composed numerous madrigals as well as dramatic music, and by combining the two, became the inventor of madrigal comedy. His compositions include the monumental Missa sopra Ecco sì beato giorno for up to 60 voices, rediscovered in 2005 after being lost for 400 years.
His son, also named Alessandro Striggio,[1] wrote the libretto for Monteverdi's Orfeo.
