The Draconimcon is the title given to several optional sourcebooks for the Dungeons and Dragons roleplaying game, providing supplementary game mechanics for dragons specifically. Different Draconomicon books have been issued for the 2nd, 3rd, and 4th editions of the Dungeons & Dragons game. The Latin-inspired name of the books loosely translates as "Book of Dragon Names".
