Dragon Harper is a science fiction novel by the American-Irish author Anne McCaffrey and her son Todd McCaffrey, part of the Dragonriders of Pern series that she initiated in 1967.

Similar to Moreta: Dragonlady of Pern and Nerilka's Story (near the end of the Sixth Pass), this book is set in a time of a pandemic that threatens human life on Pern (just before the third return of Thread, or Third Pass).

The story focuses on the character Kindan, featured in Dragon's Kin, who has taken a position as an apprentice at the Harper Hall.

The book then deals with an influenza-like pandemic that threatens the lives of holders, as the Weyrs must maintain a quarantine to keep their rosters healthy enough to fight the next Threadfall.

The story additionally explains the loss of many of the records kept prior to, during and after colonization, further reducing the Pernese connection with its off-planet origins.
