John Jarlath Dooley (6 July 1906 – 18 September 1997) was an Irish prelate of the Catholic Church who worked in the diplomatic service of the Holy See and in the Roman Curia.

On 18 October 1951, Pope Pius XII named him a titular archbishop and Apostolic Delegate to Indochina.

Taking on the role during the hardships of the First Indochina War, his area covered four countries: Vietnam, Cambodia, Laos, and Thailand.

[6] As the Geneva Accords between France and the Viet Minh divided Vietnam in 1954, he remained in Hanoi along with his secretaries, Terence O'Driscoll, S.S.C., and Dieudonné Bourguignon, S.A.M.

[4] Dooley was evacuated by air from North Vietnam for medical treatment in early August 1959, three weeks before his secretary O'Driscoll was expelled by the government and the Delegation in Hanoi was closed permanently.
