The Gaelic Athletic Association (GAA) has reached agreement with the IRFU and the FAI over the use of the 80,000-capacity stadium for rugby and soccer in 2007.
Lansdowne Road is set to close early next year for redevelopment work.
Croke Park will stage two Six Nations rugby internationals next February and at least three football games.
The football internationals are likely to take place in March, October and November of next year.
The joint-statement said that terms and conditions of the agreement would remain confidential although BBC Sport reports that the GAA could receive around £1million per game
The GAA's ruling body set aside the organisation's controversial rule 42, which banned the use of their headquarters for foreign sports, last April.
