The IRFU has confirmed Ireland's opponents for the November internationals later this year.
South Africa, Fiji and Argentina will all come to Dublin to face Joe Schmidt's side, with the chance to avenge last year's series defeat to the Springboks - despite Ireland's first win on South African soil - arriving first on Sunday 12 November.
The last time South Africa travelled to Dublin in November 2014 resulted in a 29-15 win for the home side.
Fiji will make their first ever trip to the Aviva Stadium a week later on Saturday 18 November, a match that will see just the fourth meeting of the sides in history.
The series will conclude on Sunday 25 November with a clash against the Pumas, Ireland's conquerors at the 2015 Rugby World Cup.
Argentina have not competed in Dublin since 2012, when Ireland ran out 46-24 winners.
