We report estimates of the masses of the component stars in the pre-main-sequence spectroscopic binary UZ Tau E. These results come from the combination of our measurements of the mass ratio, M₂/M₁=0.28±0.01, obtained using high-resolution H-band spectroscopy, with the total mass of the system, (1.31±0.08)(D/140 pc) M_☉, derived from millimeter observations of the circumbinary disk (Simon, Dutrey, & Guilloteau). The masses of the primary and secondary are (1.016±0.065)(D/140 pc) M_☉and (0.294±0.027)(D/140 pc) M_☉, respectively. Using the orbital parameters determined from our six epochs of observation, we find that the inclination of the binary orbit, 59°.8±4°.4, is consistent with that determined for the circumbinary disk from the millimeter observations, indicating that the disk and binary orbits are probably coplanar.
