Devon Corporation (Japanese: デボンコーポレーション) is a large company that is based in Rustboro City. Most of the locals just shorten the name to "Devon". It was a small company many years ago, but has grown by leaps and bounds. The Devon Corporations' headquarters is in a large stone building in the northern section of town.
Devon makes may useful products, many of them geared towards Pokémon training and is responsible for creating the new types of Poké Balls chiefly only found in Hoenn.
The Devon Corporation also developed a process to revive Pokémon from fossils. It can be assumed that this process developed independently of the one at Cinnabar Island's Labs.
The president of the Devon Corporation is Mr. Stone.
