Owen McCann (26 June 1907 – 26 March 1994) was a South African cardinal of the Roman Catholic Church and journalist.

He received his episcopal consecration on the following 18 May from Archbishop Martin Lucas, SVD, nuncio to South Africa.

McCann was created cardinal priest of Santa Prassede by Pope Paul VI in the consistory of 22 February 1965, becoming the first South African to receive the red hat.

He was one of the cardinal electors who participated in the August 1978 papal conclave, which selected Albino Luciani as Pope John Paul I, and the October 1978 papal conclave, which selected Cardinal Karol Wojtyla as Pope John Paul II.

McCann was reportedly a supporter of Giovanni Benelli at the latter conclave, but still gave his praise to the newly elected Wojtyla.
