History
On 4 October 1886, Pope Leo XIII established the Prefecture Apostolic of Canelos y Macas from the Vicariate Apostolic of Napo. Its name was changed to the Apostolic Prefecture of Canelos by Pope Pius XI on 19 February 1930. The prefecture was elevated to the status of Vicariate Apostolic of Canelos by Pope Paul VI on 29 September 1964. Its name was changed to the Vicariate Apostolic of Puyo on 18 May 1976.

It remains exempt, i.e. directly subject to the Holy See, not part of any ecclesiastical province.
