A simple model for primordial inflation in the context of SU(N,1) no-scale n = 1 supergravity is given. Because the model at zero temperature very closely resembles global supersymmetry, minima with negative cosmological constants do not exist, and it is easy to have a long inflationary epoch while keeping density perturbations of the right magnitude and satisfying other cosmological constraints. Specific attention is paid to satisfying the thermal constraint for inflation, i.e., the existence of a high temperature minimum at the origin.
