The "Mauthausen Trilogy", also known as "The Ballad of Mauthausen" and the "Mauthausen Cantata", is a cycle of four arias with lyrics based on poems written by Greek poet Iakovos Kambanellis, a Mauthausen concentration camp survivor, and music written by Greek composer Mikis Theodorakis. It has been described as the "most beautiful musical work ever written about the Holocaust", and as "an exquisite, haunting and passionate melody that moves Kambanellis' affecting words to an even higher level".

Michail "Mikis" Theodorakis was a Greek composer and lyricist credited with over 1,000 works.
