We evaluate the contribution of SUSY-QCD to top-charm associated production at next generation linear colliders. Our results show that the production cross section of the process e(+)e(-) --> t (c) over bar or (t) over bar c could be as large as 0.1 fb, which is larger than the prediction of the standard model by a factor of 10(8).
