Abstract: We study $\mathrm{CP}$ violating B decays in the minimal supersymmetric standard model with R-parity violation. We estimate how much R-parity violation modifies the SM predictions for $\mathrm{CP}$ asymmetries in B decays within the present bounds. The effects of R-parity- and lepton-number-violating couplings on the ratio of the decay amplitude due to R-parity violation to that of the SM can differ by one or two orders of magnitudes depending on the models of the left-handed quark mixing. It is possible to disentangle the R-parity-violating effects from those of the SM and R-parity-conserving supersymmetric models within the present bounds comparing different $\mathrm{CP}$ violating decay amplitudes. We also study the effects of R-parity- and baryon-number-violating couplings and find that the effects could be large.
