Dehn-Sommerville manifolds are a class of finite abstract simplicial complexes that generalize discrete manifolds. Despite a simpler definition in comparison to manifolds, they still share most properties of manifolds. They especially satisfy all Dehn-Sommerville symmetries telling that half of the f-vector entries are redundant. They also share other properties with q-manifolds: for every Dehn-Sommerville q-manifold G and any function g: V(G) to A={0, ..., k} with positive k, the set of x such that g(x) contains A is a Dehn-Sommerville (q-k)-manifold if not empty. We also see that for Dehn-Sommerville q-manifolds, all higher characteristics w_m(G) agree with Euler characteristic that the chromatic number is bounded above by 2q+2 and that odd-dimensional Dehn-Sommerville manifolds are flat and form a monoid under the join operation. In general, Dehn-Sommerville manifolds are invariant under edge refinement, Barycentric refinement and Cartesian products.
