The number of people accessing emergency accommodation has surpassed 14,000.
The latest data published by the Department of Housing shows that in April there were 9,803 adults and 4,206 children in emergency accommodation.
14,009 people were recorded as being homeless in April, a rise of 143 from the figure of 13,866 in March.
The figures mean there has been a 14% rise in homelessness over the past 12 months.
The total number of families who were in emergency accommodation last month was 1,996, which means 15 more families found themselves homeless in April compared to March.
The number of children recorded homeless also rose - 59 more children became homeless in April compared with the previous month.
The Minister for Housing has said there is no shortage of determination in dealing with the issue of homelessness.
Responding to today's figures, Darragh O'Brien said the biggest challenge was assisting those with no home and who are in emergency accommodation.
"We've seen significant increases in the numbers of households prevented from entering and assisted in exiting emergency accommodation in Q1 this year, but we know that the reasons people present are varied and complex," he said.
In a statement, Minister O'Brien said that increasing housing supply "is the key to resolving the current crisis and it is the absolute focus of the Government".
Homeless charities have expressed shock and dismay over the figures.
Sinn Féin's Spokesperson on Housing Eoin Ó Broin said homelessness has increased by 61% under the current Government.
He said the Government's "failing housing plan" was the cause of the rise in homelessness.
Mr Ó Broin, said the Government is "at risk of normalising those month-on-month increases" and that people he is meeting on the election campaign trail believe the levels of homelessness are scandalous.
"There is an election next Friday, and when people go to the polls - albeit in the Local and European elections - they have to remember that rising homelessness is a direct result of Fianna Fáil, Fine Gael and the Green Party," he said.
Labour leader Ivana Bacik noted that the figures offer "just a glimpse" into the true scale of the problem.
She said sky-high rents, inadequate legal protections for renters, and personal circumstances such as domestic violence had made the lives of many people precarious.
Social Democrats TD Cian O'Callaghan described Minister O'Brien's "dismissive response" to the Housing Commission’s report as "deeply problematic".
The report suggested a targeted increase in the proportion of social and cost-rental housing to 20% of the national stock.
Mr O'Callaghan added the minister needed to take "urgent action" to protect people from the trauma of becoming homeless.
Focus Ireland has called on the Government to accept and implement the key recommendations in the recently published report by the Housing Commission.
It said that the Government could act today to prioritise moving the many families and individuals out of long-term homelessness, and straightforward changes could make rapid and significant differences to people's lives.
In Dublin, the total number of people in emergency accommodation is now recorded as 10,216.
CEO of Dublin Simon, Catherine Kenny, said the increases are being driven, not by sustained high volumes of homeless presentations, but fewer people exiting homeless accommodation to tenancies.
"This is leading to more congestion in an already gridlocked housing system," she said.
Dublin Simon also pointed out that the figures do not include those rough sleeping, people in domestic violence shelters, refugees, and those on our streets seeking asylum.
Depaul has also called for recommendations made in the Housing Commission report to be implemented.
CEO David Carroll noted that the commission had advised that Ireland's housing deficit be addressed through 'emergency action’, which he said is something that the charity had been calling for consistently.
The charity has said Government housing targets need to be increased for 2025, from 33,000 homes to 50,000 homes.
