The Government has been urged to raise social welfare payments by €25 in the next budget.
Social Justice Ireland is also calling for child benefit to be hiked by €50 per month in 2024, in order to "protect the most vulnerable" of the population.
Colette Bennett, Economic and Social Analyst for Social Justice Ireland, said that the Government can "absolutely afford" these increases.
She told Newstalk: "What we're calling on Government to do is reverse the mistakes of Budget 2023, which increased the rich-poor gap by €199 across the year," she said.
"We want to see an increase in core social welfare, which would go some way to address both the cost of living pressures, but also towards the benchmark that we have been calling on Government to implement for years now.
"This is the Government's own benchmark that they implemented in 2007 and then forgot about."
Ms Bennet said that the social welfare increases would allow those on low incomes to have "a chance to maintain a decent standard of living."
"In terms of child benefit, we want to see that increased by €50 a month," she said. "The Taoiseach – when he was reinstated again in December – he came out and he said we are going to address child poverty, we are going to make Ireland the best little country to grow up in.
"That requires investment in children and part of that is to make sure that families with children have adequate incomes."
