A holocaust survivor, a Burmese human rights lawyer and the United Nations secretary general are among those shortlisted for the Tipperary International Peace Award.
The award, now in its 27th year, recognises the contribution of individuals and organisations that promote peaceful cooperation.
Homeless charities and campaigners are prominent among the nominees, with people such such as Fr Peter McVerry (Fr Peter McVerry Trust), Sr Stanislaus Kennedy (Focus Ireland) and Brother Kevin Crowley (Capuchin Day Centre) included.
Dublin resident Tomi Reichental, who was the subject of an RTÉ documentary where he attempted to trace one of his holocaust jailers from the Belsen concentration camp, is also on the shortlist, along with Burmese human rights lawyer Robert San Aung.
Mr San Aung, who has campaigned to protect members of the public and the press from Government intimidation in Burma, made a brief "respite" visit to Ireland last May.
NGO Médecins Sans Frontières also received a mention for its work combatting the Ebola virus in west Africa where it has cared for more than 7,000 patients since March 2014.
UN secretary general Ban-Ki Moon has also made the shortlist of seven. Previous recipients of the award, organised by the Tipperary Peace Convention, include Nelson Mandela, Mary McAleese and Mikhail Gorbachev.
The winner will be announced in the coming days.
