A man killed when he was walking with his daughter has been named as Martin Finn.
Mr Finn, who is in his 60s, and his daughter were walking on the R120 Newcastle Road between Lucan and Newcastle in west Dublin at about 9pm on Tuesday when the collision occurred.
The pair were struck by an SUV. His 17-year-old daughter was treated in hospital but her injuries are not believed to be life-threatening.
Gardai said the road was closed for several hours to allow forensic collision investigators on to the scene, and they also appealed for witnesses.
Four people have been killed in road accidents in recent days.
Two elderly women were struck by a car after getting off a bus in Co Louth on Monday, and another woman was killed in Callan, Co Kilkenny, on Sunday.
