We study some aspects when one consider the existence of one extra-dimension in addition to a non-commutative space-time. We present here two different examples, where the first one provides a scenario were it is possible to relate the variations on the compactification radius L and the non-commutative parameter θμν, recovering the usual Minkowski (3+1)D metric and, in the other one, we can set a simple relationship between this radius and θ, the non-commutative parameter, for the gravitational potential between a point particle and a straight cosmic string in (2+1)D.
