Menzoberranzan is a fictional city in the world of Forgotten Realms, a Dungeons & Dragons campaign setting. It is located in the depths of the Underdark, below the river Surbrin. It is famed as the birthplace of Drizzt DoŽUrden.

Menzoberranzan had its own PC game and was also a boxed gaming supplement for AD&D, with three books.

The city has 32,000 inhabitants - one-third drow and the rest humanoid slaves. The city trades poisons, tasty mushrooms, riding lizards, spell scrolls, wine, and water.

Menzoberranzan is ruled by a council of matrons from the eight greatest noble houses; the most powerful person in the city is Mother Baenre, a drow cleric who was been the single most powerful political figure in Menzoberranzan for a few thousand years.
