A group G is called smooth if its subgroup lattice L(G) has a smooth chain, and we call G totally smooth if all maximal chains in L(G) are smooth. We call G is a minimal non-totally smooth group if G is not totally smooth with totally smooth proper subgroups. In this paper we determine all finite minimal non-totally smooth groups.
