In the role-playing game Dungeons & Dragons (D&D), dragons are often depicted as having many different races, each usually based on a particular color of their scales or an affinity with an element. This classification has been used in a great deal of modern fantasy fiction.

In the fictional Wheel of Time fantasy series by Robert Jordan, the Dragon is the champion of the Light and the Creator against the evil Dark One. Although the Dark One was imprisoned by the Creator at the moment of creation, he continually seeks to break free of his prison. In each Age, the Dragon is reborn to fight the Dark One and keep him locked away from the world.

Dragons are an intelligent race that inhabit Alagaësia, a fictional fantasy world created by Christopher Paolini. They are a key part of the Inheritance Trilogy, in which dragons are a nearly extinct and magical race.

Dragon is the eighth book in Steven Brust's Vlad Taltos series, published in 1998 by Tor Books. It is the third book of the series in chronological order, largely occurring after Yendi and before Jhereg. Following the trend of the Vlad Taltos books, it is named after one of the Great Houses in Brust's fantasy world of Dragaera and features that House as an important element to its plot.
