Irish tourism, culture and sport minister Mary Hanafin has announced that more than EUR360m (£305m) will be invested across the three sectors over the next four years.
It follows the publication of the Irish government's National Recovery Plan, which also see Hanafin's department contribute EUR76m (£64m) of savings by 2014.
The funding will be targeted at the upgrade of major tourist attractions, the improvement of infrastructure in markets such as walking and heritage; and the promotion of eco-tourism. Existing sports schemes will also be supported.
Hanafin said: "All government departments are making their contribution towards the economic recovery and the government has made some very difficult choices.
"Our priority now is to continue to invest, upgrade and promote the tourism product in order to take advantage of the recovery."
