A town in northern Johto. Its motto is "Welcome to the Home of the Ninja!", because of the ninjas that once resided in what eventually became the Team Rocket HQ.

Pokémon Trainers must come to Mahogany Town in order to win the Glacier Badge from Pryce, the Mahogany Gym Leader who specializes in Ice-type Pokémon.

Mahogany is a quiet, relaxed town, and has no Poké Mart. Instead, there is a shop used by Team Rocket as a base in Pokémon Gold, Silver, and Crystal. After Team Rocket is defeated, it is converted into a store run by a little old lady.

To the north of the city is the Lake of Rage.

There are three exits out of town. To the west is Route 42, to the east is Route 44, and to the north is Route 43.
