Three UBV light curves of the short-period EB-type eclipsing binary V836 Cyg, observed in 1971, 1976 and 1980 are presented. The instability of the light curve found by previous authors is confirmed. From the observed period variation, previous light-curve analysis data and spectroscopic data, it is concluded that V836 Cyg consists of two main-sequence stars, and will undergo rapid mass exchange before terminating the main sequence.
