Pendragon, meaning "head of the dragons," may refer to:

• Uther Pendragon, mythical father of King Arthur
• Stephen R. Lawhead's Pendragon Cycle of fantasy books
• Peter Pendragon , star of Aleister Crowley's Diary of a Drug Fiend
• Pendragon (band) a British progressive rock band
• Pendragon role-playing game

Note that all of the above were named after Uther Pendragon. I'm not sure if the case below is or isn't:

• D. J. MacHale 's Pendragon Series of fantasy books
