We consider a smooth hybrid inflation scenario based on a supersymmetric SU(2)L X SU(2)R X U(1)B-L model. The Higgs triplets involved in the model play a key role in inflation as well as in explaining the observed baryon asymmetry of the Universe. We show that the baryon asymmetry can originate via nonthermal triplet leptogenesis from the decay of SU(2)L triplets, whose tiny vacuum expectation values also provide masses for the light neutrinos.
