The standardised unemployment rate in October has increased to 14.4%, up slightly from 14.3% in September, according to figures from the CSO.
There was a seasonally-adjusted increase of 2,700 people on the Live Register in the past month.
Over the last 12 months the seasonally-adjusted register has remained in the range of 441,300 to 448,700.
The CSO says that while there have been fluctuations in the Live Register over the past 12 months, the underlying trend has been flat.
The headline figure - which does not take seasonal factors into account - fell by 7,000 in October to 430,400.
Successive governments' responses to the unemployment crisis have been ineffective according to the Irish National Organization for the Unemployed.
In a statement responding to today's Live Register figures, the INOU says the Republic badly needs a co-ordinated jobs strategy which identifies potential job growth and ensures that education and training courses equip unemployed people to take them up.
