The eclipsing binary RR Leporis has been observed on 42 nights during 1982-1987 in standard U, B and V passbands. The complete light curves and photometric solutions for this binary system are presented. The preliminary elements derived by Russell-Merrill method were used as inputs in Wilson-Devinney's Differential Corrections Program. All the three light curves in UBV were treated simultaneously. Two different Mode 5 solutions, in which the secondary fills its roche lobe, fitted the light curves equally well. On comparing these photometric elements with those given by Samec et al. (1988), it was found that the solution is indeterminate because i and q are strongly correlated. In the absence of any accurate spectroscopic data, it is premature to derive absolute dimensions of the system. The most likely parameters are given.
