Ireland is to increase its contribution to the UN World Food Programme to €105 million.
The funding pledge from 2025 to 2027 is a 40% increase on funding made under the previous three-year period.
The Government has said it will directly fund the World Food Programme's (WFP) humanitarian work globally.
Agriculture Minister Charlie McConalogue made the announcement from Kenya, where he is leading an international development mission to the Horn of Africa.
"This represents our highest-ever contribution and confirms Ireland's commitment to fighting world hunger, in conjunction with WFP," he said.
"Ireland recognises the impact that conflict and climate change are having on food security and nutrition.
"Our increased funding will enable WFP globally to continue to respond to crisis-affected refugees while also working to build resilience and community integration."
Minister McConalogue called on other governments to take similar steps.
"WFP delivers food assistance to the poorest and most vulnerable people in the world," he said.
"I want to use the announcement of this increased funding to highlight the importance of continued support to the WFP and to encourage governments around the world to take steps towards giving them the reliable funding they require".
World Food Programme Executive Director Cindy McCain praised Ireland's firm commitment.
"I am grateful to the people and Government of Ireland for significantly increasing their funding to WFP for the next three years," she said.
"Their steadfast support and recognition of the critical role WFP plays in alleviating global hunger demonstrates Ireland’s firm commitment to assisting the world’s most vulnerable people," she added.
The WFP assists 80 million people in around 80 countries each year.
