I can personally suggest FreeLing [nlp.lsi.upc.edu/freeling]. It supports most languages in the iberian peninsula (spanish, portuguese, catalan (including multiple dialects), galician), and then it also includes english, italian, french, german, russian, croatian and slovene. It's also more flexible than other tools if you need to go outside those languages and customize something.
