The Chymical Wedding of Christian Rosenkreutz (German: Chymische Hochzeit Christiani Rosencreutz anno 1459) is a German book edited in 1616 in Strasbourg. Its anonymous authorship is attributed to Johann Valentin Andreae. The Chymical Wedding is often described as the third of the original manifestos of the mysterious "Fraternity of the Rose Cross" (Rosicrucians), although it is markedly different from the Fama Fraternitatis and Confessio Fraternitatis in style and in subject matter.
As one of the three foundational Rosicrucian Manifestos, the book also inspired several Rosicrucian organizations such as Order of the Golden and Rosy Cross (1750s–1790s) and Societas Rosicruciana in Anglia (1865–present).
