  We present an analysis of a devised sample of Rotation Curves (RCs), aimed at
checking the consequences of a modified f(R) gravity on galactic scales.
Originally motivated by the the dark energy mystery, this theory may serve as a
possibility of explaining the observed non-Keplerian profiles of galactic RCs
in terms of a break-down of the Einstein General Relativity. We show that in
general the power-law f(R) version could fit well the observations with
reasonable values for the mass model parameters, encouraging further
investigation on R^n gravity from both observational and theoretical points of
view.
