The mass distribution in the stellar disk of the early-type highly inclined galaxy NGC 4594 is derived based on interpretation of the observed ring-like distribution of HI as tightly wound spiral arms. Results indicate a local surface density in the stellar disk at a galactocentric distance r = 15 kpc of about 40-50 solar masses/sq pc, a disk mass of 1.14 x 10 to the 11th solar masses, and an upper limit of 10 for the average mass over luminosity ratio. The average mass to luminosity ratio for the spheroid is shown to increase from about 5 at r = 10 kpc to about 6 at r = 20 kpc. Results suggest that the stellar disk of this early type spiral resembles those of later type galaxies.
