We analyze the trace anomaly for a scalar, self-interacting, field theory in four-dimensional space-time in the framework of the stochastic quantization method. We adopt a regularization scheme at the Langevin equation level, obtaining the regularized expression for the anomaly, for a wide class of regularizing operators.
