We calculate the chiral effective superpotential in 4D N=1 , SU(N) super Yang-Mills theory coupled to chiral matter in one- and two-loop approximations. It is found that the one-loop contribution to the chiral effective potential is always finite and is expressed in terms of a specific triangle integral. The two-loop contributions generated by purely chiral vertices turned out to be finite as well. The chiral effective potential stipulated by supergraphs with gauge superfield subgraphs is finite for the supergraphs with no divergent subgraphs. In the case of the finite N=2 SYM theory, the two-loop chiral contributions to the effective action are significanlty simplified. The leading large N behavior of the chiral effective superpotential in finite super-Yang-Mills models with SU(N) gauge symmetry is studied and it is shown that the exact form in the coupling constant of the chiral effective superpotential can be found.
