I don't mean to be picky but you're asking a question that has more to it than just the tag-line.
What are the 'givens'. Are you interested in keeping in heat? Is there a water problem? Are you above or below ground? What is the climate where you live? What I CAN suggest is that you go to My Favoriate WEB Search Engine, and enter +"foundation insualation" (including the '+' and the "), and press Search. You'll get a lot of 'hits' on what you want to look at AND what's out there.
In short, if you're insulating below ground, for moisture control, a foundation drain is always in order, along with proper grading and downspout location. After that, insulate on the inside if you're finishing the basement; on the outside if you're not (good luck). My best to ya and hope this helps.
