Go to Hearthome City and go to the house next to the Pokemon Center after obtaining the National Dex. Inside the house is Bebe who is going to ask you to obtain the Eevee, say "yes" and she'll give you Eevee as long as there's at least one empty slot in your Party. You can also find Eevee in the Trophy Garden after getting the National Dex and talking to Mr. Backlot. He may tell you he found a Eevee in the garden.
I'm not sure if you can catch Eevee in Pokemon pearl but you get it as a gift from Bebe in Hearthrome City after you get the national dex.
In Pokemon Diamond and Pearl you can receive Eevee from Bebe in Hearthome city.
