We analyze the potential of TESLA and CLIC based electron-photon colliders to search for excited spin-1/2 electrons. The production of excited electrons in the resonance channel through the electron-photon collision and their. subsequent decays to leptons and electroweak gauge bosons axe investigated. We study in detail the three signal channels of excited electrons and the corresponding backgrounds through the reactions egamma --> egamma, egamma --> eZ and egamma --> vW. Excited electrons with masses up to about 90% of the available collider energy can be probed down to the coupling f = f' = 0.05(0.1) at TESLA(CLIC) based egamma colliders.
