Counting is underway across the country
An exit poll has predicted a three-way tie between Fine Gael, Sinn Féin and Fianna Fáil.
The Ipsos-MRBI poll for RTÉ, TG4, The Irish Times and UCD showed the most fractured political landscape in recent memory.
It is 22% all around with the three largest parties in the country all tied.
The exit poll of more than 5,300 people shows Fine Gael, Sinn Féin and Fianna Fáil all on 22% support.
The poll shows the Green Party on 7.9%, Labour on 4.6%, the Social Democrats on 3.4%, Solidarity-People Before Profit on 2.8% and Independents and others with 14.5% of the vote.
Young people seem to have come out to support Sinn Feinn as they stood at 31.8% between 18 to 24 year olds in the exit poll.
