Cathal O'Shannon (23 August 1928 – 22 October 2011) was an Irish journalist and television presenter. He was a reporter with The Irish Times, and television reporter/presenter and documentary film maker with RTÉ. He was awarded lifetime membership of the Irish Film & Television Academy in 2010, to which he said it was "particularly gratifying that it occurs before I pop my clogs". The Irish radio and television broadcaster Terry Wogan described O'Shannon as possibly the greatest Irish television journalist of the 20th century.
