EO Aurigae is an early-type eclipsing binary of large amplitude. A photoelectric light curve consisting of 316 V observations is presented. The period does not seem to be changing significantly. A solution for the elements of the system is derived and a theoretical light curve constructed from these elements is found to fit the data well. These new elements differ considerably from those published previously. Approximate values for the masses, luminosities, spectral types, and radii are determined for the two stars.
