Sinn Féin's Mary Lou McDonald says it is time for action on the issue
Thousands of people are expected to turn out for a pro-choice march in the capital today.
The 5th Annual March for Choice is organised by the Abortion Rights Campaign, and will begin at 2.00pm.
The march will gather at the Garden of Remembrance from 1.30pm, marching to Leinster House for 4.00pm.
It coincides with the annual Global Day of Action for Safe and Legal Abortion.
Representatives from the 65 member organisations of the Coalition to Repeal the Eighth Amendment will take part.
The theme of this year's march is 'Rise and Repeal' - a comment on what the Abortion Rights Campaign say is the failure of the Republic to live up to the ideals of equality set out in the 1916 Proclamation.
Speaking in advance of the event, ARC spokesperson Linda Kavanagh said: "100 years on from the Easter Rising, the equality promised in the 1916 proclamation hasn’t been realised.
"Women, trans men and non-binary people who may need to access abortion in Ireland, North and South, still don’t have the right to choose."
ARC spokesperson Janet O'Sullivan added: "We are tired of the delay tactics being used by successive governments who bury their heads in the sand, ignoring the urgent need and desire for change.
"We are tired of being told to wait - tired of being told we need a ‘calm and measured debate’ while our contributions to this debate are silenced or belittled."
