Cross products in F^n, F a finite field

Let F be a finite field with p^m elements; p a prime, m a positive natural number. Consider the vector space with vectors ordered ntuples of F's elements, and scalar multiplication and vector addition defined pointwise. Call it F^n.
For which p, m and n can a cross product be defined in F^n?
