• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.

Term used in roleplaying game circles for a player - often literally the DM's girlfriend, sometimes a younger family member - who is getting special treatment from the gamemaster due to an out-of game personal relationship, specifically because the GM either wants to curry favor with them or is afraid of incurring their ire. This is often at the expense of other players, who showed up at the table to participate equally, but have somehow ended up playing sidekicks to the Dungeon Master's Girlfriend.

This trope is much older than, and not limited to gaming situations, though. Before there were RPGs, it was was a situation that would arise in theatre, film, and TV — the director would give his girlfriend a large or important role, or a producer would insist that his current girlfriend be given a part as a condition for his backing. In most cases, she is not competent enough to handle the role; in some, she's not competent at all.

This is not a trope about someone that does something only because their significant other is doing it.

In case of roleplay, the girlfriend or sibling might actually have an advantage by knowing the DM better than the other players without any favouritism coming into play.

Examples of Dungeonmaster's Girlfriend include:

Comic Books

  • Knights of the Dinner Table: The queen of this trope would be Heidi Jackson. She doesn't merely manipulate a local GM boyfriend, she actually acquires control of the Hackmaster RPG intellectual property (their world's Dungeons and Dragons) as the creator's heir's guardian and after a couple of game sessions decided to radically overhaul the game system in ways that led to rioting in the gaming community.
    • By contrast Sara, the Gamemaster's cousin, subverts this trope so much that it's almost an inversion. B.A. cuts her even less slack than he does the other players, but he's constantly accused of giving her 'cousin favoritism' if she tastes success that the other players don't get. Especially if the reason why she was the only one to get anywhere because of her Genre Savvy, her niceness to in-game characters, or not being insane.


  • Bullets Over Broadway. In this case, a mobster's girlfriend.
  • Underworld has Kate Beckinsale, who met the director on set and is now married to him. Guess who all the action in 4 films centers on.
  • In a very similar vein, Milla Jovovich in the Resident Evil film series met the director on set and they are now married. Might explain some of her telekinesis, super strength, replication and Healing Factor when the video games are mostly about Badass Normal people fighting zombies and mutant creatures.


  • One very early Dragon magazine short story (by Roger Moore... no, not him) used this trope in-character, when a tavernful of male adventurers were bragging of their power, achievements, and connections to still-greater beings. A woman at a private table kept snickering at their boasts, until they got fed up and confronted her with sexist remarks. She sneered at their petty claims, threw back her cloak to expose her magnificent armor, weapons, and other bling, and proclaimed: "My husband is the Dungeon Master." The boasters all looked up, anticipating a vengeful bolt from the blue, then very quickly evacuated the tavern when they realized no such retribution was coming.

Tabletop Games

  • Built into the rules of the D20 version of Munchkin is a feat called "Shagging the DM". It has only one prerequisite, and it's in the title. It allows you to reroll one roll every 30 minutes. (The feat's description also points out that if you qualify for it, you probably don't need it.)

Web Comics


 Gabe: The skeleton lashes out at you, Vin, for... [Vin glares] damage! He missed! Again. And then... he died. So you get a million XP. And all the gold. And you win the whole game, forever.

  • It seems the DM's younger sister gets away with a lot more silly behaviour in Darths and Droids than the rest of the cast. For good or for better, she comes up with most of Star Wars unnusual Fauna.

Web Original

  • Variation with Asenath Summerisle in The Binder of Shame; she's introduced as Deviant Boy's girlfriend while he's running a game. She herself is an okay gamer and ends up getting along fine with the guys, but he warps the entire game to revolve around her Mary Sue character; "She got to play hero while the rest of us swam through raw sewage being chased by vaguely alien sex slavers."
