Ozanari Dungeon (Japanese: おざなりダンジョン, Hepburn: Ozanari Danjon) is a comedy fantasy manga series by Motoo Koyama which was serialized in Monthly Comic Nora from November 1987 to November 1996.

The manga series was adapted into a three-episode OVA series titled Ozanari Dungeon: The Tower of Wind (おざなりダンジョン 風の塔, Ozanari Danjon: Kaze no Tō) from Toshiba EMI.

Ozanari Dungeon is an adventure manga set in a fantastical Sword and Sorcery world while occasionally showing a few pieces of anachronistic technologies such as missiles and airships.

This manga follows the adventures of a group of mercenaries: the barbarian Mocha (the main character), the rogue Blueman, and the mage Kiriman.

The scale becomes quite large, with whole nations going to war and dragon(s) which can destroy the world.
