Kenny: We'll watch Scotland closely
Taoiseach Enda Kenny said people will be watching closely to see what changes are implemented in Scotland after it rejected independence.
"The people of Scotland have spoken. We respect their democratic decision that Scotland should remain as part of the United Kingdom," he said.
"We are committed to deepening and strengthening the already close relationships across these islands.
"Attention will now turn to the changes likely to take place following the referendum, particularly in terms of devolution of powers. This process will be closely followed in Ireland."
Mr Kenny said Ireland remains Scotland's neighbour, friend and partner across political, economic, cultural and many other spheres, and relations with Britain have never been stronger.
"We look forward to working with all parties across these islands in the years ahead," he said.
He also cited the Good Friday Agreement as the historic template for harmonious relations between Britain and Ireland.
Foreign affairs minister Charlie Flanagan said the independence referendum debate was rich and passionate with both sides sharing a common concern for the best interests of the Scottish people.
"I share the hope that all parts of Scottish society can now come together in a constructive and inclusive way in shaping Scotland's future within the UK," he said.
"The strong bonds and historic links between us all run deep and are well-known.
"We will be in close contact with London, Edinburgh and other administrations as discussions proceed on enhanced devolution for Scotland and on the political changes across the UK as outlined by Prime Minister (David) Cameron in his statement this morning."
