Italian tenor Luciano Pavarotti will use his weekend concert in Dublin as a forum for the United Nations global anti-poverty campaign.
The acclaimed singer will perform in Ireland on Saturday
Saturday's concert at The Point will include short films on the Millennium Development Goals - which the UN hopes will cut poverty by half by 2015.
The films are to be shown throughout his global farewell tour.
UN coordinator Eveline Herfkens called it a "great opportunity" for Pavarotti "to add his great voice to this cause".
"We are the first generation that can end poverty," said Herfkens.
"This great opportunity given by Pavarotti during his series of concerts is of great importance to reach many people around the world."
The 69-year-old opera star has been a UN Messenger of Peace since 1998.
Speaking in South Africa in April, he said he was proud to be associated with "this valuable and vital organisation and will do whatever I can to help its work".
Last month Pavarotti was forced to reschedule two forthcoming UK appearances due to ill health.
An 11 June concert at the Madejski Stadium in Reading has been moved to 1 July 2006, while his 9 July concert at Chatsworth House, Derbyshire will take place almost a year later, on 8 July 2006.
Pavarotti's spokesperson said he had been forced to move the dates as a consequence of neck surgery in March to repair two vertebrae.
"His doctors reported that he recovered very quickly from his operation and have now advised that the second and final stage of this procedure must take place at the beginning of June 2005," said Terri Robson.
The farewell tour has already seen Pavarotti perform in Ukraine, South Africa, Mexico and the United Arab Emirates.
