We show that any analytic $f(R)$-gravity model, in the metric approach,presents a weak field limit where the standard Newtonian potential is correctedby a Yukawa-like term. This general result has never been pointed out but oftenderived for some particular theories. This means that only $f(R)=R$ allows torecover the standard Newton potential while this is not the case for otherrelativistic theories of gravity. Some considerations on the physicalconsequences of such a general solution are addressed.
