Ireland has secured a seat on the UN Security Council for two years.
A total of 128 countries voted for Ireland for one of the two 'Western Europe and other states' seats - meeting the required two-thirds majority.
Norway secured the other seat in the category, winning two more votes than Ireland.
Ireland faced a challenge from NATO members Canada and Norway to win the seat on the influential council, with both spending more on their bids than Ireland.
The Irish Government spent €840,000 on its campaign for the seat over the last three years.
Efforts included events featuring U2 and Riverdance, as well as a diplomatic push from Taoiseach Leo Varadkar and Tánaiste Simon Coveney in many of their dealings with foreign dignitaries.
Minister Coveney had described today's UN vote as "arguably the biggest day for Irish foreign policy for 20 years".
Ireland last won a temporary Security Council seat in 2001.
The Security Council has a total of 15 seats, including five permanent members (China, France, Russia, the US and UK).
