We report the photometric properties in BVR bands for the resolved bright supergiant stars in the dwarf galaxy Holmberg II. The color-magnitude diagrams and color-color diagram of 374 resolved stars indicate that the majority of the member stars are supergiant stars with a wide range of spectral type between B-K. A comparison with theoretical evolutionary tracks indicates that the supergiant stars in the observed field have progenitor masses between ${sim}10M_{igodot};and;20M_{igodot}$. The exponent of luminosity function in V is in good agreement with those of the Small and Large Magellanic Clouds.
