We present evidence for elastic pion Compton scattering as observed via the Primakoff process on nulcear targets. We find production cross sections for ..pi../sup -/A..--> pi../sup -/..gamma..A on lead and copper of 0.249 +- 0.027 and 0.029 +- 0.006 mb, respectively, in agreement with the values expected from the one-photon-exchange mechanism of 0.268 +- 0.018 and 0.035 +- 0.004 mb in the region of our experimental acceptance. This reaction provides a clean test of the Primakoff formalism.
