Brian O'Driscoll will be the face of Ireland's bid to host the 2023 Rugby World Cup.
The former Ireland captain and world's most capped player has been named as bid ambassador, which will see him undertake a largely lobbying role.
Former Irish foreign minister and ex-Ireland international full-back Dick Spring will chair the bid's board.
Hugo MacNeill, who led Ireland's joint Rugby World Cup Working Group, will also join the board.
Philip Browne and Paraic Duffy, chief executives of the Irish Rugby Football Union and the Gaelic Athletic Association, will sit on the board along with Ulster Rugby chief Shane Logan.
Former Irish deputy prime minister Spring will chair the oversight board, with Dr David Dobbin named chief executive.
France, Italy and South Africa are also in the running to stage the tournament and countries have until the middle of next month to express an interest.
This year's Rugby World Cup is being hosted by England, while Japan has been awarded the 2019 tournament.
Further appointments, including individuals with sporting, business and major events experience, will be made to Ireland's bid team in the coming weeks.
Ireland's intention to bid to host RWC 2023 was announced at a ceremony in Armagh last November.
IRFU chief executive Philip Browne said it is "a very exciting opportunity for Ireland".
"While competition will be fierce for what is one of the most prized events in world sport, we will leave no stone unturned in putting together a world-class case for Ireland to host what would be a hugely successful Rugby World Cup in 2023."
