Where do you get Charmander on Pokemon pearl?

You can't get Charmander in Pokémon Pearl. Charmander is a Fire-type starter Pokémon from the Kanto region, and Pokémon Pearl is set in the Sinnoh region.

The starter Pokémon you can choose from in Pokémon Pearl are:

* Turtwig (Grass)

* Chimchar (Fire)

* Piplup (Water)

While there's no way to obtain Charmander directly in Pokémon Pearl, you can use trading with other players to get it. You'd need to trade with someone who has a Charmander from another game.
