Recent work in two brane Randall-Sundrum models has shown that the radion can drive parametric amplification of particles on the TeV brane leading to a stage of cosmology similar to preheating. We consider radion induced preheating as a mechanism for electroweak scale baryogenesis and estimate the baryon to entropy ratio for some regions of parameter space. We also predict an upper bound for the radion mass which makes this baryogenesis mechanism testable. Finally, we verify some assumptions with numerical calculations of the 1+1 dimensional Abelian Higgs model.
