Nguy?n Phúc C?nh (1780–1801), also known as Prince C?nh, was the eldest son of the Vietnamese Prince Nguy?n Phúc Ánh, the future Emperor Gia Long.
At the age of seven, he famously visited France with the French Catholic Father Pigneau de Béhaine to sign an alliance between France and Vietnam.
Although Prince C?nh was the legitimate heir to the throne, he died before his father, and none of his descendants ascended the throne after his half-brother Nguy?n Phúc Ð?m was chosen by Gia Long.
