Dom António II Ribeiro (21 May 1928 – 24 March 1998) was a Portuguese cardinal of the Roman Catholic Church, and Patriarch of Lisbon from 1971 until his death in 1998.

Meanwhile, in 1960 he took on a weekly tv program called Dia do Senhor (The Lord's Day), and collaborated with several religious magazines and newspapers, beyond his own publications.

On Manuel Gonçalves Cerejeira's retirement as Patriarch in 1971, Ribeiro was appointed his successor and, a year later, also Vicar Apostolic of the Portuguese Military.

He was created Cardinal-Priest of Sant'Antonio da Padova in Via Merulana[2] by Pope Paul VI, on 5 March 1973, which made him, at the age of 44, the youngest cardinal in the XXth century since Cerejeira himself, forty-four years earlier.

Recognised as a man of compromise (and markedly less close to the Estado Novo government than Cerejeira had been), Ribeiro was nevertheless very determined in defending the rights and privileges of the Church in his country.
