Dorian (Japanese: リュウジ Ryuuji) is a character of the day in the Pokémon anime. He appeared in Just Add Water. His English voice actor is unknown and his Japanese voice actor is 遠近孝一 Kōichi Tōchika

Dorian is a Water-type Pokémon trainer who runs the unofficial Coastline Gym near a beach south of Blackthorn City. Dorian puts on sychronized swimming shows with his Pokémon because he's a big fan of Daisy, Violet, and Lily. Misty in particular was enraged by Dorian's statement that Lily was prettier than she was. Dorian defeats Ash, but Dorian later respects Misty after she shows off her Psyduck's powerful Confusion attack.

Dorian's gym battles take place underwater, with trainers using SCUBA gear to remain with their Pokémon.
