The contribution of the pair annihilation process in relativistic electron-positron jets to the γ-ray emission of blazars is calculated. For pair densities >10^9^cm^-3^ in the jet the annihilation radiation will dominate the inverse Compton radiation, and due to its bump-like spectrum may explain reported spectral bumps at MeV energies.
