Iron Island
From Bulbapedia, the community-driven Pokémon encyclopedia.
Iron Island a.k.a. Steel Island is a small island off the northwestern coast of the Sinnoh mainland. It is said that a trainer named Gen, considered by many to be similar to Aron that starred in Pokemon Movie Lucario and the Mystery of Mew, gives the player a Riolu Egg in this location. Riolu, as many have already known, is the pre-evolution of Lucario.
