The trip will be the first such Royal visit since Ireland gained independence from Britain.
The date for the historic visit has not been released but it is widely expected it will take place in May. The Queen will be accompanied by The Duke of Edinburgh.
This year marks the centenary of the visit by the Queen's grandfather, King George V, to what was then Southern Ireland.
"President McAleese is pleased to announce that Her Majesty Queen Elizabeth II has accepted an invitation to visit Ireland this year", the office of the Irish President said.
"The dates of the visit and the programme will be announced jointly by Aras an Uachtarain and Buckingham Palace in due course."
The Irish Government said it welcomed the imminent trip.
"The visit will mark a further improvement in the very good relations between Ireland and the United Kingdom."
Northern Ireland First Minister Peter Robinson has welcomed the announcement.
He said: "The news of a visit by Her Majesty to the Irish Republic will be welcomed by all right-thinking people throughout the United Kingdom and that country as a positive development.
"It is a sign of the normalisation of relations between our two countries that such a visit by our Head of State will be taking place.
"I would urge Republicans to afford Her Majesty the same degree of respect shown by people in the United Kingdom to Mary McAleese", the DUP leader added.
'Premature'
Sinn Féin President Gerry Adams said the visit was premature.
"The President has invited the English monarch and Sinn Féin respects her right to do so. However we believe this visit is premature and we expect our views to be respected also.
"As Republicans Sinn Féin is very aware of the symbolism of a state visit by Queen Elizabeth of England and of the offence it will cause to many Irish citizens, particularly victims of British rule and those with legacy issues in this state and in the North," he added.
However, Mr Adams said it was an indication "we are living in changed and changing times".
SDLP leader Margaret Ritchie said the visit symbolised the "new relationship between Britain and Ireland".
"Both the Queen and the President have played no small part in signalling an end to old enmities and a blossoming of an excellent new relationship between Britain and Ireland", she said.
"I am sure the Queen will be given a very warm Irish welcome and I hope that even those who historically take issue with the British monarchy will show a new spirit of generosity and maturity that shows our country really is moving on."
Ulster Unionist Leader Tom Elliott "warmly" welcomed the news.
"This is an example of the increasing normalisation of relations between two neighbouring sovereign states and it should be welcomed by all in society", he said.
Alliance Leader David Ford said: "This is a further and extremely significant step forward in building positive relationships between all the people of these islands. I believe that this exciting news will be welcomed by many across the island."
Outgoing Taoiseach Brian Cowen began the process of inviting the Queen to visit Ireland when he met the Prime Minister David Cameron last year.
He said he wanted to see the official engagement before President Mary McAleese leaves office in 2011.
A Downing Street spokesman said: "The Prime Minister is delighted that Her Majesty the Queen will be visiting Ireland. The visit symbolises the strength of the relationship between our nations and the bond between the British and Irish people."
