The Chymical Wedding of Christian Rosenkreutz 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.

Johannes Valentinus Andreae, a.k.a. Johannes Valentinus Andreä or Johann Valentin Andreae, was a German theologian, who claimed to be the author of an ancient text known as the Chymische Hochzeit Christiani Rosencreutz anno 1459. This became one of the three founding works of Rosicrucianism, which was both a legend and a fashionable cultural phenomenon across Europe in this period.
