UBV and light curve data on the binary system ADS 9019 are reported and the geometry of the pair is discussed. The 1950.0 coordinates, magnitudes, colors and HD spectral types for the binary, a comparison and a check star are furnished, along with 402 UBV observations of the nonvarying ADS 9019 primary. Orbital elements were employed to generate theoretical light curves. The data indicate an almost identical pair, one being slightly smaller and cooler than the other. The constant light variation with strongly inflected maxima and minima of equal depth categorizes the object as a W UMa contact binary.
