If you mean the kind that come premade in a bag, then no; I've had regular potato chips like that but not sweet potato ones, though I know they do make them.

If you mean the other kind of chips, though, I have had sweet potato fries before. They're pretty good, especially with a bit of powdered sugar. There was actually a restaurant back home that would serve them with a side of this great apple butter-based BBQ sauce to dip them in; that stuff was the best.
