Just over 30% of candidates in the General Election are women, just slightly higher than the 2016 figure.
At the close of nominations yesterday there were 531 candidates in the race, of which 162 are women.
The Chief Executive of the organisation 'Women for Election' said they were disappointed with the number of women running.
Ciairín de Buis said: "While it's very welcome news that there is a woman running in every constituency, for the first time ever, we need to be more ambitious than that.
"Women aren't a minority group, we are more than half the population and political parties need to wake up to the fact that we need political leadership which represents us all."
Women for Election is a not-for-profit organisation which encourages and supports women in Ireland to run for politics.
Current legislation requires parties to ensure at least 30% of their candidates are women, or they lose half their State funding.
Women for Election said: "Fine Gael just scraped over the quota at 30.5%; Fianna Fáil (31%), Labour (32%) and Sinn Féin (33%) didn't do much better."
Ms de Buis said the numbers of women on the ticket for People Before Profit (38%), the Green Party (41%), and the Social Democrats (57%) show there are "plenty of women who are politically engaged, active and ready to run out there, right now.
"You’d have to wonder why the other parties cannot recognise this fact."
