  We argue that Poincar\'e symmetry can be implemented in NCFT if we allow the
parameter of noncommutitive deformation $\theta^{\mu\nu}$ to change as a
two-tensor under the corresponding space-time symmetry. The implementation is
consistent with the definition of $\theta^{\mu\nu}$ in terms of space-time
coordinates and with the Moyal star product. Inspired from the standard
definition of a variational symmetry we found a universal way to correct the
implementation of the Poincar\'e symmetry by a term proportional to the
variation of $\theta^{\mu\nu}$ in such a way that the new transformation define
a symmetry of the theory. Finally we present as an example the case of NCYM
theory and comment about the obstructions to implement generalized space-time
symmetries in NCFT like conformal or diffeomorphism transformations.
