We derive the absolute magnitude of RR Lyrae stars by two independent maximum-likelihood estimations, using Hipparcos proper motion and parallax data, respectively. By applying the statistical parallax method to 99 Halo RR Lyrae stars, we obtain the mean absolute magnitude = 0.69 +/- 0.10 at <[Fe/H]> =- 1.58. Independently of this method, we furthermore derive the M_V - [Fe/H] relation from Hippparcos parallaxes for 125 RR Lyrae stars including negative ones by the method of Ratnatunga & Casertano. We obtain M_V = 0.91(+/- 0.88)+0.21(+/- 0.63)[Fe/H]. For 99 Halo RR Lyrae stars, = 0.65 +/- 0.33 is also derived.
