Harrison (Japanese: ハヅキ Hazuki) is a character from the Pokémon anime. He began his journey in Littleroot Town, Hoenn, and competed in the Silver Conference. His Japanese voice actor is 鳥海勝美 Katsumi Toriumi, his Latin-American Spanish voice actor is Enzo Fortuny and his English voice actor is Wayne Grayson.

He first appeared in Pop Goes the Sneasel. Along with Ash and his friends, Harrison tried to ward off a wild Sneasel that was guarding the sacred Ho-Oh flame. Harrison promised that he would capture it. Using his Houndoom, he did just that.

After many cameos during the qualifying rounds of the Silver Conference, Harrison appeared next in Can't Beat the Heat, where he and Ash began their six-on-six battle. It continued in Playing with Fire and Johto Photo Finish. In the latter episode, Harrison defeated Ash, but went on to lose to Jon Dickson.

It was Harrison who convinced Ash to go to the Hoenn region. He told Ash all about Professor Birch and about all the Pokémon that Ash had probably never seen before.
