Prison officers received compensation of €2.7 million last year, due to assaults on duty.
The average award was nearly €25,000.
On behalf of the state, the Criminal Injuries Compensation Tribunal runs a scheme that compensates people who have suffered due to violent crime.
It also runs a similar scheme for prison officers who are injured on duty.
There was a four-fold increase in awards to prison officers who were the victims of violent crime last year.
In 2019, 36 people got payments, coming to €603,000 in total.
Last year 110 prison officers got compensation, coming to over €2.7 million.
Jim Mitchell, deputy general-secretary of the Prison Officers Association, says the awards normally relate to very serious incidents.
He said: "You're talking about somebody that was struck with a blade, burnt, scalded or had bodily fluids thrown over them, and then incurred a significant amount of sick leave.
"We all know the difficulty of drugs within prisons - the routine application of those would be with needles and syringes. Those can then sometimes be used as weapons."
The Irish Prison Service says every assault on a member of staff is treated very seriously, and appropriate action is taken.
Figures released in 2019 showed an increase in the number of injuries suffered by prison officers dealing with non-compliant prisoners.
