The flavor-changing top-quark decay $tto c h$, where $h$ is the lightest CP-even Higgs boson in the minimal supersymmetric standard model, is examined in the R-parity-violating supersymmetric model. Within the existing bounds on the relevant R-parity-violating couplings, the branching fraction for $tto c h$ can be as large as about $10^{-5}$ in some part of the parameter space.
