  We study perturbative aspects of noncommutative field theories. This work is
arranged in two parts. First, we review noncommutative field theories in
general and discuss both canonical and path integral quantization methods. In
the second part, we consider the particular example of noncommutative $\Phi^4$
theory in four dimensions and work out the corresponding effective action and
discuss renormalizability of the theory, up to two loops.
