After getting the National Dex, go to Route 229 and there will be MEW floating above the pond, I think he is there because it resembles a similarity to Faraway Island in Pokemon Emerald and it is a rainforest and MEW lives in the rainforest because of the book entrys in the Pokemon Mansion in FR/LG: Deep in the rainforest, we discovered a new pokemon, we cristended the newly found Pokemon as "MEW". Happy hunting :)

It isn't possible to catch mew in Pokemon diamond. You need an action replay cheat cartridge.
No you cannot.
Mew and Mewtwo are not found anywhere in the Sinnoh region.
you don't, you migrate it from Pokemon ranger, have fun on you're game, I can catch every Pokemon exept mew.
Its impossible.Although you may see your friends throw out Mew from time to time, and Mew up for grabes on the global trading system, it is impossible to catch Mew on Pokemon Diamond. This doesn't mean you can't have her on your game.If you catch a mew on Pokemon Fire Red or Leaf Green, you can migrate it to your game if you have completed the game.
