  We consider the problem of Newtonian singularity in the wide class of higher
derivative gravity models, including the ones which are renormalizable and
super-renormalizable at the quantum level. The simplest version of the
singularity-free theory has four derivatives and is pretty well-known. We argue
that in all cases of local higher-derivative theories, when the poles of the
propagator are real and simple, the singularities disappear due to the
cancellation of contributions from scalar and tensor massive modes.
