Noncommutative geometry is the study of geometry/topology on a space where the underlying algebra is noncommutative, so that the order of operations in which one performs actions becomes important. I don't actually know much about this besides that for some reason a noncommutative sphere seems to arise in quantum mechanics through analysis of the angular momentum representation of $su(2)$, so maybe someone else should fill in.
