In the framework of R-parity violating supersymmetry, we investigate the time dependent CP asymmetry SφKS anomaly of B →φKS decay. When the values of the weak phase φ in the R-parity violating coupling fall into certain parameter spaces (246° < φ < 263°) we find that this anomaly can be easily ex- plained; at the same time, the branching ratio of B →φKS decay can also be in agreement with experimental measurements.
