Klefki, known in Japan as Cleffy (クレッフィ), is a Pokémon species in Nintendo and Game Freak's Pokémon franchise. Designed by Ken Sugimori and first introduced in Pokémon X and Y. Klefki is a steel and fairy Pokémon that is known for constantly collecting keys. It was designed by Pokémon graphic designer Mana Ibe and was inspired by old mansions and secret keys. A short film about Klefki called Pikachu, What's This Key For? premiered as an opener for the 17th Pokémon film.

Klefki received a largely negative reception, though it gained the most attention among generation VI Pokémon prior to release. While multiple critics felt that it was a weird or terrible design, other critics spoke more highly of Klefki, defending it and other Pokémon based around inanimate objects. Critics also discussed how nostalgia impacts people's perception of Pokémon, citing the Pokémon Magnemite from Pokémon Red and Blue in comparison to Klefki. It also became a powerful Pokémon in competitive play, being a highly effective Pokémon in Pokémon X and Y's competitive scene.
