A total of 14,303 people needed to access emergency homelessness accommodation last month, including 9,899 adults and 4,404 children under the age of 18.
The latest figures, which are an overall increase of 144 people on May, were released by the Department of Housing as part of its monthly homeless report.
In a statement outlining the figures, the department said a total of 14,303 people received emergency accommodation across the country in June.
This figure is up 144 people, or 1%, on the same figures for May.
The 14,303 people includes 9.899 adults and 4,404 children. A total of 2,093 families are included in the figures.
The same report also said that between April and the end of June a total of 786 adults and 259 families exited emergency accommodation after alternative arrangements were found.
This figure is up 9.4% on the same period last year.
In a statement on Friday afternoon, Minister for Housing and Fianna Fail TD Darragh O'Brien said the latest report "unfortunately records a further increase in the number of individuals accessing emergency accommodation".
"Supporting individuals and families facing homelessness is a top priority for this Government.
"My department continues to work closely with local authorities and their service delivery partners in the provision of this support to enable households to secure an exit to a tenancy or to avoid entering emergency accommodation in the first place."
Minister O’Brien said increasing the supply of housing is "critical to address homelessness" adding that the Government is making funding of €242 million available for homeless services this year - an increase of 12.6% on last year.
"My department and this Government recognise the significant and complex impacts of homelessness on individuals and families and will continue to focus our efforts on preventing homelessness and reducing the numbers of homeless individuals and families experiencing homelessness," he said.
In a statement, the Dublin Simon Community said the number of people nationally in emergency accommodation now exceeds the capacity of Hill 16 in Croke Park.
Catherine Kenny, CEO of Dublin Simon, said there is an "urgent need for comprehensive, coordinated action to address the root causes of homelessness and alleviate the strain on emergency accommodation resources".
"It is not enough to say that housing is a challenge in this country – we all know it is – the question is what the government intends to do about it in the months before we go to the polls. The time for action is now," she added.
