Pokémon FireRed Version (Japanese: ポケットモンスターファイアレッド Pocket Monsters Firered[4]) and Pokémon LeafGreen Version (Japanese: ポケットモンスターリーフグリーン Pocket Monsters Leafgreen) are a pair of core series Generation III games that are set in the Kanto region. They were released in Japan on January 29, 2004, in North America on September 9, 2004, in Australia on September 23, 2004 and in Europe on October 1, 2004.

As the first remakes in the Pokémon franchise, the games revisit the original pair of Pokémon games, Pokémon Red and Green Versions. The remakes feature the characters, plot elements, and challenges from the originals, along with several updates introduced in Generation III.

The Game Boy Advance Wireless Adapter was initially included with the games when they were first released, eliminating the need for Game Link Cables when trading between the two games (and later Pokémon Emerald). In later copies, it was sold separately.

FireRed and LeafGreen went on to become the second best-selling games on the Game Boy Advance, only behind Pokémon Ruby and Sapphire. They also received Nintendo's Player's Choice awards.

FireRed and LeafGreen are the first of two remakes to take place in the region of Kanto, and were followed by Generation VII games Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! in 2018.
