The Birth of Tragedy from the Spirit of Music (German: Die Geburt der Tragdie aus dem Geiste der Musik) is an 1872 work of dramatic theory by the German philosopher Friedrich Nietzsche. It was reissued in 1886 as The Birth of Tragedy, Or: Hellenism and Pessimism (German: Die Geburt der Tragdie, Oder: Griechentum und Pessimismus). The later edition contained a prefatory essay, “An Attempt at Self-Criticism”, wherein Nietzsche commented on this earliest book.
