The average rent in Dublin is now €1,620, new figures show.
Data from the Residential Tenancies Board and Economic and Social Research Institute (ESRI) shows that rents in the capital were up €141 in the third quarter of this year.
That's compared to the same period the previous year.
That's an increase of nearly €12 per month.
Nationwide, rents are continuing to rise, but at a slightly slower rate than recent years.
The RTB suggests that Rent Pressure Zones appear to be slowing the rate of rent increases - in particular for existing tenancies.
The board also says there's been an overall decrease in landlords despite unprecedented demands for housing.
The figures show 1,778 fewer landlords compared to 2015.
Rosalind Carroll, director of the RTB, explained: "Unsurprisingly, Dublin is experiencing the most acute rent pressures with fewer than 15% of tenancies agreed at less than €1,000 per month, as compared to 70% elsewhere in the country.
"We can also see the Dublin rental sector is dominated by apartments (73%) as compared to less than one-in-two elsewhere."
She added: "If we are to meet demand and ensure a well-functioning rental sector, then we need more landlords and different types of landlords to offer market options.
"With many landlords leaving, it is increasing strain and pressure and this must be addressed."
