It is two wins from two for Ireland in this season's Six Nations.
Five penalties from Johnny Sexton, and one for Ian Madigan have seen Joe Schmidt's side beat France 18-11 at the Aviva.
Ireland led 12 to 6 at half-time, increasing their lead to 18 in the second half. But a late game try from France meant there was a narrow gap between the two teams heading into the closing minutes.
It was a tense wait for the whistle following penalties for France and a number of scrums that could have put the visitors ahead. However, Ireland managed to stay ahead for their six points win.
Next up for Ireland, in a fortnight's time, an England side that ran in 6 tries in a 47-17 defeat of Italy at Twickenham earlier today.
In tomorrow's Six Nations fixture, Wales take on Scotland at BT Murrayfield. Kick-off there is at 3pm.
In this evening's Guinness Pro 12 action, Munster managed a 33-16 win against Cardiff Blues at Irish Independent Park.
It was Denis Hurley, Jack O’Donoghue and Ronan O’Mahony with tries for Munster in a win that has put the team at the top of the Pro12 table.
