Voting in the Presidential election and the blasphemy referendum begins this morning.
Polls around the country opened from 7 o'clock, and will stay open until 10 o'clock tonight.
On the presidential ballot, there will be six names - Michael D Higgins, Seán Gallagher, Gavin Duffy, Joan Freeman, Liadh Ní Riada and Peter Casey.
A number of polling stations across the country saying turnout is only half of what we saw for the abortion referendum in May.
It looks likely that less people will vote this time than did in 2011, when the turnout was 56%.
This afternoon in Dublin voting numbers have been slow across the county, as low as 10 per cent in some booths just after lunchtime.
Votes are also being cast in the referendum on blasphemy.
A Yes vote would mean deleting the reference to blasphemy in the constitution, while a No vote would leave the constitution as it is currently.
Voters are advised to bring their voting card and official ID with them to the polling centres.
