Das Floß der Medusa is a 1967 secular oratorio by the German composer Hans Werner Henze. It is regarded as a seminal work in the composer's alignment with left-wing politics.

Méduse was a 40-gun Pallas-class frigate of the French Navy, launched in 1810. She took part in the Napoleonic Wars during the late stages of the Mauritius campaign of 1809–1811 and in raids in the Caribbean.
