We present evidence for elastic pion Compton scattering as observed via the Primakoff process on nuclear targets. We find production cross sections for -A-A on lead and copper of 0.2490.027 and 0.0290.006 mb, respectively, in agreement with the values expected from the one-photon-exchange mechanism of 0.2680.018 and 0.0350.004 mb in the region of our experimental acceptance. This reaction provides a clean test of the Primakoff formalism.
