The White Dragon is a briefly-mentioned dragon species from the How to Train Your Dragon book series.
The White Dragon is pure white and has one horn on the middle of its forehead. Not much else is known about White Dragons, and only a partial picture was drawn by the author (seen in the infobox at right). We do know it is large enough to carry at least two people at a time. Because most riding dragons are classified as Sky Dragons, it can be presumed White Dragons are, too.
