Cornelius Christopher Cremin (6 December 1908 – 20 April 1987) was an Irish diplomat who was born in Kenmare, County Kerry.
His brother, Francis Cremin, became a leading academic canon lawyer who framed a number of key church documents.
After travelling to Ascain, the legation eventually made its way to the new French capital, Vichy, where it set about looking after the needs of Irish citizens, many of whom had been interned, as they had British passports and had been sending political reports.
Warned to leave Berlin before the Soviets arrived, Cremin spent the last weeks of the war near the Swiss border.
In 1945, he was sent to Lisbon, where he met the authoritarian leader António de Salazar and attempted to revive Irish trade.
