"Alone Again" is a power ballad written and released by the American heavy metal band Dokken on their 1984 album Tooth and Nail. The single reached #64 on the Billboard Hot 100 and #20 on the Hot Mainstream Rock Tracks chart. The song was written by singer Don Dokken and bassist Jeff Pilson.

Its lyrics talk about a man's depression after a break-up. The music video had a story similar to a lot of other power ballads. Almost 70% of it is filmed in black and white along with some coloured scenes. It shows the band performing the song live along with some shots of Don Dokken being alone in a room.
