Pope John Paul II visited Ireland from Saturday, 29 September to Monday, 1 October 1979, the first trip to Ireland by a pope. Over 2.5 million people attended events in Dublin, Drogheda, Clonmacnoise, Galway, Knock, Limerick, and Maynooth.

It was one of John Paul’s first foreign visits as Pope, who had been elected in October 1978. The visit marked the centenary of the reputed apparitions at the Shrine of Knock in August 1879.
