From Bulbapedia, the community-driven Pokémon encyclopedia.
This is a list of Pokémon by their evolution family. That is, it is a list of Pokémon in their National Pokédex order, however, it includes later-released evolutions and pre-evolutions closer to the first Pokémon in their family to be released. This means that Pichu will appear before Pikachu, instead of at its National Pokédex position of 172, and Magby and Magmortar will appear next to Magmar. Evolution families are named by their basic evolutionary form. For example, although Azurill is the lowest Pokémon in its evolutionary line, it is still known as the Marill family, because Marill was released first.
The methods of evolution listed include all legitimate manners of inducing said evolution in the main series games, Pokémon Colosseum, and Pokémon XD, with the first listed being the first introduced method, which itself may or may not be able to be done as of Generation V depending on the Pokémon.

- Professor Rowan is said in the games to have studied Pokémon evolution and determined that 90% of all Pokémon are related in some way by evolution. As of Generation V, with 102 (54 normal, 48 legendary) Pokémon out of 649 total not evolving, this is quite accurate, as a little over 84% of all Pokémon undergo at least one evolution before being fully evolved. Excluding legendaries, which do not evolve as a rule, brings this percentage to just over 91%.* In previous generations:
- 25 (20 normal, 5 legendary) Pokémon did not evolve in Generation I, with percentages of 83% including and 86% excluding legendary Pokémon.*
- 43 (32 normal, 11 legendary) Pokémon did not evolve in Generation II, with percentages of 83% including and 87% excluding legendary Pokémon.*
- 73 (52 normal, 21 legendary) Pokémon did not evolve in Generation III, with percentages of 81% including and 87% excluding legendary Pokémon.*
- 77 (42 normal, 35 legendary) Pokémon did not evolve in Generation IV, with percentages of 84% including and 91% excluding legendary Pokémon.*
- By far, most three-stage evolution families were introduced in Generation I, with 27 such families having their roots there (though not necessarily their most unevolved or most evolved forms). Because of branch evolution, 29 of the second-evolution Pokémon can count themselves as members of a Generation I evolution family. Generation V has the second most, with 19 three-stage families (none due to branching). Generation III has the next most, with 16 three-stage families that end in 18 Pokémon (again due to branching), while Generation II and Generation IV have the least, with only nine and six families, respectively, that end in a third member.
- Generation V, however, has introduced the most original three-stage evolutions, as many of the three stage-evolutions stemming from Generation I include Pokémon not introduced in the same generation as their evolutionary relatives.
- Generation V is the only generation not to introduce cross-generational evolutionary relatives.
