Tourists are spending more this year than they were for the same period in 2014.
CSO statistics show overseas visitors coming to Ireland spent an estimated €590m in the first three months of 2015.
The number of trips to Ireland by holidaymakers also rose considerably, with an increase of 13.3pc recorded.
Minister for Tourism Paschal Donohoe welcomed the increase in tourist spending. He said the Government would continue to ensure that the strong economic return was maintained throughout the year.
“The statistics published today show that revenue from overseas visitors has also increased. This again confirms that the measures undertaken by the Government to boost Ireland’s attractiveness as a destination are working,” Mr Donohoe said.
“In the first quarter of 2015 alone, our overseas visitors spent an estimated €590m in Ireland, which is an enormous contribution to our economy and an increase of 10.5pc on the corresponding period of 2014.
“We are not resting on our laurels, however. Tourism Ireland has a strong marketing programme in place for the remainder of 2015 to ensure that this strong economic return is maintained,” he added.
The main increase in revenue came from visitors from mainland Europe, which grew by 17.5pc, while spending from North American tourists grew by 16.8pc.
Failte Ireland CEO Shaun Quinn welcomed the positive figures.
“Tourism’s strong growth continues and, on current trends, we may be looking at a record year for overseas visitors in 2015,” he said.
