  We study scalar field and string theory on non commutative q-deformed spaces.
We define a product of functions on a non commutative algebra of functions
resulting from the q-deformation analogue to the Moyal product for canonically
non commutative spaces. We then give the general procedure to define scalar
field and classical string theories on the mentioned spaces, we argue that the
resulting theories will have enlarged sets of both spacetime and internal
symmetries which can be used to study gravitational effects due to the
q-deformation.
