Nguyễn Văn Thinh (Vietnamese pronunciation: [ŋwiən˦ˀ˥ van˧˧ tʰïŋ˧˧]; 1888 – 10 November 1946, Saigon) was the first President of Cochinchina.

He felt a loss of face when the French negotiated with the Viet Minh, ignoring his government.

Dr. Nguyễn Văn Thinh was born in 1888, in an aristocratic family in the South of Vietnam.

He was the first valedictorian of the Indochina School of Medicine in 1907, and one of the first Vietnamese medical students who successfully passed the examination for Interne Doctors at the Hospital of Paris (Interne des Hôpitaux de Paris).

Dr. Nguyễn Văn Thinh started his political career as a Constitutionalist by holding Phan Chu Trinh's funeral ceremony.
