True Dragons:
There have been many dragons over time: Adamantite, Amethyst, Black, Blue, Brass, Bronze, Brown, Chiang Lung (River), Cloud, Copper, Crystal, Deep, Emerald, Faerie, Fang, Gold, Green, Li Lung (Earth), Lung Wang (Sea), Mercury, Mist, Pan Lung (Coiled), Red, Sapphire, Shadow, Shen Lung (Spirit), Silver, Song, T’ien Lung (Celestial), Topaz, Tun Mi Lung (Typhoon), White, and Yellow at a quick glance over the "true" dragons. This page is intended as a guide to finding information on these dragons.

The "basic 10" chromatic and metalic dragons are found in the Monster Manual and in the SRD. The Forgotten Realms Campaign Setting details five more dragons: brown, deep, fang, shadow, and song. Oriental Adventures covers seven eastern dragons, which can be identified by their two names in the list above. The psionic gem dragons can be found in WotC's Psionic Handbook Web Enhancement.
The remaining six dragons have not been officially converted, but can be found on the Creature Collection: Adamantite, Cloud, Faerie, Mercury, Mist, and Yellow.

In addition to the true dragons, there are many dragon-like creatures in the game. Though they have the "Dragon" type, they lack the features real dragons share.
The SRD lists the dragon turtle (Monsters: D), the pseudodragon (Monsters: N, O, and P), the wyrven (Monsters: U, V, and W), and the half-dragon template (Monsters: Templates). The Creature Catalog has converted two more such creatures: the firedrake and ice lizard.
