"Is This Happiness" is a song by Lana Del Rey written with Rick Nowels. It was released on her second major-label studio album Ultraviolence, serving as a bonus track only available for purchase on the iTunes deluxe edition of the album.
"Is This Happiness" is a stripped-back piano ballad with soft vocals and production. Kevin Rutherford of Radio.com referred to it as the "lighest and perhaps prettiest" song from Ultraviolence. Lyrically, the song is about weighing the good and bad that comes from a relationship.
