We present analytical potential-density pairs in three dimensions for thegravitational field of galaxies, obtained by thickening the multipolarexpansion up to the quadrupole term. These may be interpreted asgeneralizations of the Miyamoto and Nagai potential-density pairs. With asuitable restriction on the possible values of the multipole moments, thedensity distributions are positive and monotone decreasing functions of theradial and axial coordinates
