In terms of an effective Lagrangian we investigate the possibilities of probing anomalous top quark couplings, t t H, γt t, Z t t and tWb at the future linear colliders. It is found that probing anomalous top quark couplings, t t H, γt t, Z t t and tWb at the future linear colliders. It is found that at a linear collider with a c.m.energy √ s ∼ 0.5-1.5 TeV and a high luminosity of 10-1000 fb-1, e+e- → t t H is an ideal process in probing anomalous t t H couplings. We also study in detail the effects of anomalous couplings on t t spin correlations in the top pair production as well as the top quark decay processes with three bases (helicity, beam line and off-diagonal bases). Our results show that with a c. m. energy √ s ∼ 0.5-1 TeV and a high luminosity of 1-100 fb-1, the anomalous couplings γt t, Z tt and tWb may be sensitively probed.
