We present a class of graviton-dilaton models in which a homogeneous isotropic universe, such as our observed one, evolves with no singularity at any time. Such models may stand on their own as interesting models for singularity-free cosmology, and may be studied further accordingly. They may also arise from string theory. We discuss critically a few such possibilities.
