Do I need a passport to go to Mexico?

No, you do not. You do need a passport card, book or enhanced drivers licence to come back by land.

If you are flying, yes, if you are an American citizen, you need a passport book to board and outbound international flight.

Where were you the past year - living in a cave?

You can get into Mexico without a passport - but you need one to get back into the USA/Canada

What are you, still in elementary school?? Anyone with half a brain who isn't completely challenged knows that you need a passport. Google it and stop wasting everyone's time asking questions that can be easily researched.

Yes

You need a passport to go to mexico.

But why waste money?...just crash through the border like what most mexicans do...

Of course you do!!!!

Anyways... if you are traveling by car you can pass the border without it but you will need it to return to US.

If you are flying, you will need it to board the plane.

Is Mexico in the U.S. or is it a different country?

Why are you people so ignorant?

Do Mexicans have passports when they come here?

yes. But since you had to ask... I hope you are not traveling alone :)

Yup.
