Photoelectric UBV light curves of AR lacertae made in one season during 1981-82 are presented. Although the shape of the light curves in the outside eclipses shows a strong distortion, the scatter of observations as well as phase coverage are better than those previously available. Fourier coefficients are derived from the V-light curve and the observed curve successfully rectified to the Russell model. Light curve solutions are computed and the geometrical and physical parameters of AR Lac are derived as <TEX>$a_s$</TEX>=0.182, <TEX>$a_g$</TEX>=0.341, j=<TEX>$86^{circ}$</TEX>3, <TEX>$L_s$</TEX>=0.372, <TEX>$L_g$</TEX>=0.628, k=0.53, <TEX>$X_s$</TEX>=0.85, <TEX>$X_g$</TEX>=0.4.
