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.

In the anime

Many evolution items have appeared in the anime. The first one to appear was the King's Rock in Ring Masters, which Ash won in the Sumo Conference and Misty's Poliwhirl later used to evolve itself into a Politoed in Outrageous Fortunes. Another King's Rock appeared in A Crowning Achievement, which was found on a rock after the water level in the local river dropped dramatically; Alice's Slowpoke used it to evolve into a Slowking.

A DeepSeaScale and DeepSeaTooth appeared in The Evolutionary War where the people in the A-B-C Islands where having an argument over which Pokémon was best, Gorebyss or Huntail.

A King's Rock, two DeepSeaTeeth, and two DeepSeaScales appeared in Showdown At Linoone as some of the items Tokin picked up.

In One Big Happiny Family!, Brock carved and made an Oval Stone for his newly born Happiny, which later helped her evolve into a Chansey in The Brockster is In.

In Fighting Fear with Fear!, Ash got a Razor Fang from Gary Oak and he used it to evolve his Gligar into a Gliscor.
