Ireland will take on South Africa, Australia and a European Tier Two nation at the Aviva Stadium for the autumn internationals in November 2014.
South Africa, currently number two in the IRB world rankings, provided the opposition for the opening fixture of the 2012 Guinness Series and will again be Ireland's first opponents in the autumn of 2014 as the two sides square off on Saturday 8 November.
A week later on Saturday 15 November, Joe Schmidt's side will take on "a leading European Tier Two nation" at the same venue.
Georgia, who have serious RWC15 qualification ambitions, are the most likely opposition for this Test.
Ewen McKenzie's Australia, who beat Ireland in Dublin last month, will return to the capital on Saturday 22 November.
The 2013 series saw Ireland lose to both Australia and New Zealand, with a sole victory gained against Samoa.
