"The public have spoken," he said. "The result appears to be resounding in favour of repealing the Eighth Amendment."
Speaking in his Wicklow constituency count centre, the Health Minister Simon Harris said Ireland has a new message for women facing crisis pregnancy.
"Up to this point we have been saying, 'take the plane' or 'take the boat,'" he said.
"We are now saying 'take our hand... we want to be able to care for you with compassion in our own country.'"
Mr Harris said he will ask the Cabinet for permission to begin drafting the legislation on Tuesday.
There's been widespread welcome of the result from human rights groups.
The Irish Council for Civil Liberties (ICCL) said it was an "overwhelming" vote.
Executive director Liam Herrick said: "This resounding and emphatic vote by the Irish people to repeal the Eighth Amendment is an historic victory for women's rights.
"This vote demonstrates that Ireland in 2018 is a more caring and compassionate society that recognises the harm and terrible injustice that has been caused by this constitutional provision.

While Amnesty International said: "Today the people of Ireland sent a powerful message to women and girls that their human rights and reproductive health matter.
