Also sprach Zarathustra, Op. 30 (Thus Spoke Zarathustra or Thus Spake Zarathustra) is a tone poem by Richard Strauss, composed in 1896 and inspired by Friedrich Nietzsche's philosophical novel of the same name. The composer conducted its first performance on 27 November 1896 in Frankfurt. A typical performance lasts half an hour.

The work has been part of the classical repertoire since its first performance in 1896. The initial fanfare – titled "Sunrise" in the composer's program notes – became particularly well-known after its use in Stanley Kubrick's 1968 film 2001: A Space Odyssey.
