The national Crime Victims Helpline has seen a 52% increase in the number of calls since 2015.
Its 2018 Annual Report shows over 4,463 contacts were made by phone, e-mail, text and post from people seeking support and information.
The helpline received 1,872 calls to their freephone number - 116-006.
Similar to previous years, the most common crimes that people were impacted by last year were assault (27%), harassment (24%) and burglary (9%).
The report also highlights a campaign to bring greater awareness of new legal rights for victims of crime.
Last June, Justice Minister Charlie Flanagan launched a 'Know Your Rights' resources - a booklet, website and video designed to explain the new rights as they relate to each aspect of the criminal justice system.
Executive director of the Crime Victims Helpline is Michele Puckhaber.
She says: "People share their fears with us after experiencing a burglary or an assault, they express their frustration at the slowness of the criminal justice system - and they look to us to provide guidance, a listening ear and hope that they will feel 'normal' again.
"Nobody should suffer alone or in silence."
Brendan Lynott, chairperson of the helpline, adds: "Crime continues to exist, and every day people become victims and suffer a range of consequences.
"Crime Victims Helpline will continue to support, inform and empower victims and all those impacted by crime."
