Well, that depends very much on your level. If you are completely new to Spanish (like I was), you'll need to bootstrap the learning process with something really basic.
I started using an audio course from Pimsleur, teaching me to say "Where is the hotel?" etc.
After that, I still needed material of the simpler kind suitable for foreigners. There are a bunch of such podcasts, for example:
When you're getting bored with the stuff for foreigners, you'll find a wealth of "normal" podcasts in Spanish. Don't worry if you don't understand every word, as long as you get the basic gist.

http://www.notesinspanish.com (very beginner-friendly, some parts in English)
http://teresasanchez.biz/podcast/ (slightly more advanced, all in Spanish)
http://www.spanishpodcast.org/ (also a bit more advanced)

When I started I very much enjoyed a podcast on astronomy, at http://universo.iaa.es/
Spain's national radio, RNE, has pretty much all of their programming available as podcasts, at http://rtve.es
The BBC has a rather good daily news podcast at http://www.bbc.co.uk/podcasts/series/mh/
After a while you'll be ready for something more difficult, for example:
Etcetera podcast is two guys in Buenos Aires philosophizing in a rather entertaining way, at http://etceterapodcast.com/
Pretty much the same, but with three guys in Spain and more swear words, is Kafelog, at http://www.kafelog.com/
