I don't doubt it's known as "Dia de Muertos" over there, but technically "Dia de los Muertos" is also correct in Spanish. It's the day of the group of people that are dead.

Just like you would say "Dia de las Madres", "Dia de los Niños", no?

I always heard "día de muertos". The first time I heard "día de los muertos", I thought it was some kind of protest over some massacre. We have many prominent groups of dead people in Mexico. :-(

Yes, as a Spanish speaker (from Spain) if I didn't know that it is called "Día de Muertos" in Mexico it would sound strange to me.
