There were 9,907 people accessing emergency accommodation in March.
The latest homelessness figures from the Department of Housing show there was a drop of 241 people last month compared to February.
March's total includes more than 3,300 children.
There were fewer families in emergency accommodation, with a decrease of 122 in a month.
Housing Minister Eoghan Murphy said the Government is working with local authorities and NGOs to ensure the safety of everyone in emergency accommodation during the COVID-19 pandemic.
He said: "Despite the current challenges work is taking place across the country to move people into homes.
“We continue to add capacity to the system where needed to allow for isolation and social distancing and are working closely with the HSE.
"Again, I want to thank all those staff who are working on the front line through local authorities and our partner NGOs each and every day.”
Homelessness charities have welcomed the decrease in March, but stressed there cannot be any increase once the current coronavirus restrictions begin to be eased.
Wayne Stanley of the Simon Communities said some families 'on the brink of homelessness' have been able to remain in their home due to the moratorium on evictions.
He observed: "Once the health crisis eases, we need to ensure that there are preventative supports in place to help these families and individuals stay out of homeless emergency accommodation.
"We believe that work should be a part of ongoing planning to unwind the restrictions put in place due to the health crisis and should continue as part of any new government strategy on homelessness. "
