Donal Raymond Lamont OCarm (27 July 1911 – 14 August 2003), was an Irish-Rhodesian Roman Catholic bishop and missionary who was best known for his fight against white minority rule in Rhodesia (now Zimbabwe).

In 1946, he volunteered to go to the new Carmelite mission in Southern Rhodesia (now Zimbabwe), and went with two companions to Umtali (now known as Mutare),[1] in the east of the country, and close to the border with Mozambique.

Throughout the letter, he repeatedly contrasted the attitudes and actions of the Government of the Federation of Rhodesia and Nyasaland and the white minority with those that he regarded as authentically Christian.

In particular he condemned the difference in educational opportunity available to children of the two racial groups, and accused the government of obstructing efforts by Christian missionaries to improve educational provision for black children: "Missionaries have been waiting, quite literally for years, for permission from the State to open the most elementary kind of village schools which the African people require and demand and are willing to erect at their own expense; and the applications, detailed and in writing, are still ungranted."

Amongst his criticism, Lamont wrote an open letter to Ian Smith, then Prime Minister of Rhodesia, saying: "Far from your policies defending Christianity and Western civilization, as you claim, they mock the law of Christ and make communism attractive to the African people."

He was detained in Salisbury Hospital, where he received treatment for injuries caused in a car accident,[8] while the Rhodesian Government quietly made arrangements to just have him deported.
