We derive the disk I-band luminosity function from the Zheng et al. sample of\~1400 disk M dwarfs observed with the Hubble Space Telescope. We adopt aGalactic-height-dependent color-magnitude relation to account for themetallicity gradient above the Galactic plane. The resultant I-band luminosityfunction peaks at M_I~9.5 and drops sharply toward M_I~10.5.Comment: 2 pages, 1 eps figure, submitted to Ap
