The carrier announced that it plans to restore this route from October 26th, offering five flights a week.
Enda Corneille, director of corporate affairs at Aer Lingus, said that Newcastle will serve as an important gateway for people travelling between Ireland and the north-east of England.
In the past the connection has been popular with customers ranging from football fans to business travellers to leisure tourists.
Chris Sanders, head of airline relations at Newcastle Airport, said: "We are delighted that Aer Lingus is reintroducing its service to Newcastle this winter.
"The Dublin route is our busiest international low-cost route and has become very popular for business and leisure trips in both directions. These additional flights will greatly benefit business and tourism activities at each end of the route."
Dublin is home to a number of attractions that make it popular with tourists, including the Guinness storehouse and Dublin Castle.
