Cuyen (; 1580–1615) was a Manchu prince and eldest son of the Jurchen ruler Nurhaci, the early patriarch of the Qing dynasty. An accomplished warrior, Cuyen was instrumental in the consolidation of Nurhaci's authority among rival Jurchen clans. He also served as the primary civil administrator for intermittent periods in the regime founded by Nurhaci. Eventually, however, he lost favour with his father because he tried to cast sorcery spells against other princes, and was placed in solitary confinement. He died in captivity a few years later.
