Interlayer magnetoresistance as a function of field and temperature with fields parallel and perpendicular to current direction in the organic superconductor {kappa}-(BEDT-TTF){sub 2}Cu[N(CN){sub 2}]Br was measured. For H{parallel}I, the isothermal magnetoresistance R(H) displays a peak effect as a function of field. For H{perpendicular}I, R(H) increases monotonically with field. Comparison of the peak field with the H{sub c2}(T) data suggests that the peak in R(H) occurs in the mixed state. We analyze the data in terms of the resistively shunted Josephson junction model and the density of states fluctuation model.
