Terraining contests are a special kind of contests held on the Hive Workshop, where the contestants are to use the World Editor in Warcraft III to make a special still-standing terrain screenshot, matching the specific contest theme. Terraining contests are also held for the Starcraft II users, with same rules.

Most contests are hosted by administrators in the Arena, but smaller contests are also found throughout the Hive, as in the social group Kaelicious.
