An evolution-inducing held item is an item which makes the Pokémon holding it evolve when a certain event happens, such as if the Pokémon is traded or leveled up. The item disappears once the Pokémon has evolved. For evolution-inducing items that are not meant to be held, see the page on evolutionary stones.
