Three new species of Mimosa endemic to the Brazilian Cerrado biodiversity hotspot are described and illustrated. Mimosa cavalcantina, M. gustavoi and M. venosa are assigned to subser. Polycephalae for having its diagnotic morphology, including unarmed branches, leaves with a pair of pinnae, a fimbriate paleaceous calyx, and filaments shortly monadelpous at the base. We summarize geographic distributions, habitats, phenology, and conservation status for each of the new species, compare them with morphologically similar congeners, and discuss their systematic positions.<br/>Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)<br/>CNPq: 305570/2021-8<br/>CNPq: 307747/2019-0<br/>Sistema de Autorizacao e InformacAo em Biodiversidade/Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renovaveis (SISBIO/IBAMA)<br/>Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)<br/>
