A differential calculus, differential geometry and the E-R Gravity theory are
studied on noncommutative spaces. Noncommutativity is formulated in the star
product formalism. The basis for the gravity theory is the infinitesimal
algebra of diffeomorphisms. Considering the corresponding Hopf algebra we find
that the deformed gravity is based on a deformation of the Hopf algebra.
