Abstract We consider the spin-averaged nucleon forward Compton scattering amplitude in heavy baryon chiral perturbation theory including all terms to order $$\mathcal{O}(q^4 )$$ . The chiral prediction for the spin-averaged forward Compton scattering amplitude is in good agreement with the data for photon energiesω≦110 MeV. We also evaluate the nucleon electric and magnetic Compton polarizabilities to this order and discuss the uncertainties of the various counter terms entering the chiral expansion of these quantities.
