Nguyễn Phúc Cảnh (1780–1801), also known as Prince Cảnh, was the eldest son of the Vietnamese Prince Nguyễn 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 Cảnh was the legitimate heir to the throne, he died before his father, and none of his descendants ascended the throne after his half-brother Nguyễn Phúc Đảm was chosen by Gia Long.
