A third body with a mass M3 ≅ 2.2 M_sun; has been discovered in the system RU Mon from the period variations observed over 80 years. Parameters of the long-period orbit have been determined: P3 = 67.6 yr, a3sin i3 = 8.36 AU, e3 = 0.4, ω3 = 230°. The limits on the third light have been obtained from analysis of the photoelectric light curve: L3V < 0.05. This means that the third body cannot be a single star on the main sequence. A new value of the apsidal motion velocity has been obtained: ω= (1°.034±0°.042) yr-1, corresponding to an apsidal period U = (348±15) yr. The apsidal parameter value, k2,1 ≅ k2,2 = 0.0061, determined from observations is in good agreement with the theoretical values for models of main-sequence stars.
