A pokémon ranger is a class of Trainer that debuted in the Generation III games. They come in male and female variations, dress in sturdy orange and black clothing, and carry a length of rope. Unlike the Rangers of Fiore Almia, and Oblivia , Rangers in Hoenn, Sinnoh and Kanto collect and train Pokémon just like other regular Pokémon Trainers. However, they are still primarily concerned with protecting wild Pokémon, keeping the environment safe, and making sure travelers do not get injured or lost when walking through the wilderness, as they mention in their battle dialog.

They are not Pokémon Trainers, as their goals and methods for interacting with Pokémon are very different. Specifically, they harness the power of certain Pokémon and utilize them to help defend nature.

Pokémon Rangers use Capture Stylers to calm and control wild Pokémon to help them solve ecological problems, defeat criminals using Pokémon to commit crimes, and arrest Pokémon poachers, acting as a sort of cross between a police officer and park ranger. After a Ranger becomes a good Ranger, they have a small chance of becoming Top Rangers with many new privileges.

Pokémon Rangers usually have only one Pokémon - known as their "Partner", that is with them at all times, and has been trained to a high level. Pokémon Rangers do not usually send Pokémon to battle each other directly, but generally use the Pokémon with them to power up the energies and extra settings on their Capture Stylers or to distract wild or enemy Pokémon with attacks that are not directly offensive.
