Game Boy: Entire Pokémon Sounds Collection CD (Japanese: ゲームボーイ「ポケモン」のサウンドがまるごと入って、遊べるCD) is the official soundtrack release for Pokémon Red, Green, and Blue. It contains all of the background music and sound effects used in the games, all of which were composed solely by Junichi Masuda, who is credited in the soundtrack. This includes Pokémon cries and Pokédex entries read by "Dexter", Ash's Pokédex, being the only soundtrack ever released to contain these sounds. The CD came with a map and stickers listing the 151 Pokémon at the time.

This is the only core series game soundtrack so far to not be announced for an international release.

Tracks 1-45 of disc 1 contain the background music used in the games. Tracks 46-98 of disc 1 and tracks 1-98 of disc 2 are "Dexter"'s enunciation of the Pokédex entries for each one of the 151 Pokémon from Generation I, with the voice being from Shin'ichirō Miki. Track 99 of disc 2 plays a techno-style instrumental music; when it's over, the sound effects used in-game are played.

Only Japanese titles are available as it was released exclusively in Japan. The English titles are unofficial translations adapted from the official English titles of Pokémon FireRed & Pokémon LeafGreen: Super Music Collection.
