We discuss early cosmology in theories where the fundamental Planck mass is close to the TeV scale. In such theories the standard model fields are localized to a (3+1)-dimensional wall with {ital n} new transverse sub-millimeter sized spatial dimensions. The topic touched upon include: early inflation that occurs while the size of the new dimensions are still small, the spectrum and magnitude of density perturbations, the post-inflation era of contraction of our world while the internal dimensions evolve to their final {open_quotes}large{close_quotes} radius, and the production of gravitons in the bulk during these two eras. The radion moduli problem is also discussed. {copyright} {ital 1999 American Institute of Physics.}
