One in five parents are experiencing poor mental health.
Children's charity Barnardos, says almost a quarter of Irish parents feel anxious most of the time(23%).
19% feel overwhelmed, one in ten (9%) feel depressed most of the time, while almost one third feel burnt out or exhausted most of the time.
Parents also reported how their children are impacted when they're experiencing mental health struggles with more than one in ten (12%) saying it had a considerable negative impact on their children, and almost half (48%) say it had a moderately negative impact on their children.
Barnardos CEO Suzanne Connolly, says more needs to be done to help parents more comfortable talking about mental health struggles.
"As a society, we have made considerable progress in making children and young people feel ok and comfortable talking about their mental health.
"We now need to make similar progress in normalising and helping parents to feel comfortable discussing and talking about mental health in the context of being a parent.
"Approximately 30% of families we are supporting have issues around parental mental health, making it one of the main issues families we support currently face."
The research found parents said mental health issues could affect their ability to parent as effectively and as positively as they would like.
More than a quarter said it reduced their patience (26%), more than one their said it caused emotional detachment from their children (36%), while almost one in five said it day-to-day parenting tasks were impacted by mental health issues (18%).
The research was carried out by Amárach Research with a nationally representative group of 300 parents, and 15 one-to-one interviews.
