James Cornelius van Miltenburg O.F.M., also known as Alcuin van Miltenburg (14 September 1909 - 14 March 1966), was a Dutch prelate of the Catholic Church who was a missionary bishop in Pakistan, the first bishop of Karachi and of Hyderabad, Pakistan.
He was ordained a Priest of the Order of Friars Minor on 31 March 1935.
Pope Pius XII named him the first Bishop of Karachi on 20 May 1948[1] and he received his episcopal consecration on 3 October.
When the status of the delegation was raised to of an internuncio, a status that anticipates the appointment of an official with rank of ambassador and an inappropriate role for the ordinary of a diocese, van Miltenburg led the internunciature as its chargé d’affaires and the office of internuncio remained vacant until after his departure from Karachi.
[4] Pope transferred him to the newly created Diocese of Hyderabad, Pakistan, allowing him to keep the personal title of archbishop.
