The Pope will be visiting the country for the World Meeting of Families on August 25th for a two-day visit.
The emoji, which features the leader of the Catholic Church's face against a backdrop of the Irish flag, was made available on Tuesday and can be triggered by using the hashtags #PopeInIreland, #PápaInÉirinn, #WMOF2018 and #FestivalOfFamilies.
"The visit of Pope Francis is one of the biggest events happening in Ireland this year and naturally many people will be using Twitter to discuss his time here," Karen White, Twitters' Director of Public Policy for Europe said.
"We want to encourage everyone across the world to join the conversation on Twitter about his visit to Ireland so we've created this special emoji for people to use."
Twitter has previously introduced event-specific hashtags and emojis for popular events including the World Cup and Eurovision.
But this isn't the first time the Pope, who uses Twitter himself has had emojis created by the social media site to celebrate his trips.
Twitter unveiled similar emojis when the Pope visited the United States and Latin America.
