What is Mew’s National Pokédex number?

Mew’s National Pokédex number is 151.

Mew is the final entry in the original National Pokédex, following Mewtwo at number 150. It is a Psychic-type Mythical Pokémon associated with the first generation of games.

Mew was a secret addition to Pocket Monsters Red and Green. It was not normally obtainable through ordinary gameplay, and Nintendo did not publicly promote its existence at the games’ launch. A 1996 CoroCoro Comic giveaway helped turn Mew into a major subject of rumors and player interest.

Mew is sometimes confused with Mewtwo because their names and lore are connected. Mewtwo is an artificial clone created from Mew’s genetic material, but the two occupy separate Pokédex positions and are distinct Pokémon.
