Nation of Two is the second studio album by Australian singer-songwriter Vance Joy. The album was announced on 12 January 2018, with Vance Joy explaining: "Nation of Two describes a perfectly self-contained couple; their world beginning and ending at the bed they share, the car they ride in, or any other place where they're together... the idea that their love for each other gives them their bearings; a point of reference that makes sense of life." The concept originally appeared in the Kurt Vonnegut novel Mother Night.
