Reginald Michael Cawcutt (25 October 1938 – 5 August 2022) was a South African Roman Catholic prelate.
He studied for the priesthood at St John Vianney Seminary in Pretoria and was ordained by Archbishop Owen McCann on 9 July 1962.
In 1966, he made a three-day pastoral visit to the remote island of Tristan de Cunha, where he administered the sacraments to the small Catholic community of 50, which rarely saw a priest.
As auxiliary bishop, he would live in Milnerton, a suburb on the Table Bay coast, near where he had been raised.
Cawcutt blamed the scandal on the conservative U.S.-based organization Roman Catholic Faithful, which had infiltrated the now closed website (which had been known as "St. Sebastian's Angels") and traced posting addresses.
