  We discuss cosmological models in six-dimensional spacetime. For
codimension-1 branes, we consider a (4+1) braneworld model and discuss its
cosmological evolution. For codimension-2 branes, we consider an infinitely
thin conical braneword model in the presence of an induced gravity term on the
brane and a Gauss-Bonnet term in the bulk. We discuss the cosmological
evolution of isotropic and anisotropic matter on the brane. We also briefly
discuss cosmological models in six-dimensional supergravity.
