The Affair will air exclusively on Sky Atlantic in both the UK and here in Ireland.
The Golden Globe-winning Showtime drama starring Dominic West and Ruth Wilson will premiere in May. Sky has also picked up the rights for the show's upcoming second season.
The Affair explores the emotional and psychological effects of an extramarital affair between Noah Solloway (West) and Alison Bailey (Wilson).
The story is told separately from each of the protagonist's perspectives, using their distinct memory biases to both misdirect and intrigue viewers.
Sky Atlantic director Zai Bennett said: "I'm delighted we have secured The Affair for Sky Atlantic.
"Its intricate storytelling and phenomenal acting sit perfectly on the channel, further cementing our channel's position as the home of quality drama in the UK."
