This is a listing of dungeons in both Ragnarok Online and Ragnarok Online II. Some RO dungeons and most RO2 dungeons are instanced, meaning a party of adventurers can go through their own version of the dungeon without being bothered by players outside of the party.

Several dungeons in Ragnarok Online require the completion of their corresponding access quests in order to enter them. The Expansions subcategory is available for dungeons that are part of the Global Project.

Starting in 2010, Gravity began adding nightmare mode to dungeons in response to player outcry that monster difficulty was significantly nerfed post-Renewal.
