Baryon charge radii and quadrupole moments are calculated in a quark model generalized to an arbitrary number (N_c) of colors. Several relations among the charge radii and quadrupole moments are found. In particular, a previously derived relation between the neutron charge radius and the N-->Delta transition quadrupole moment is shown to hold for physical baryons as well in the large N_c limit.
