                      driving the appearance of non-trivial, exotic topological
                      spin textures and emerging symmetry-broken phases, flat
                      electronic bands in 2D materials, including graphene, are
                      nowadays a relevant topic in the field of spintronics. Here,
                      via europium doping, single spin-polarized bands are
                      generated in monolayer graphene supported by the Co(0001)
                      surface. The doping is controlled by Eu positioning,
                      allowing for the formation of a-valley localized single
                      spin-polarized low-dispersive parabolic band close to the
                      Fermi energy when Eu is on top, and of a π* flat band with
                      single spin character when Eu is intercalated underneath
                      graphene. In the latter case, Eu also induces a bandgap
                      opening at the Dirac point while the Eu 4f states act as a
                      spin filter, splitting the π band into two spin-polarized
                      branches. The generation of flat bands with single spin
                      character, as revealed by the spin- and angle-resolved
                      photoemission spectroscopy (ARPES) experiments, complemented
                      by density functional theory (DFT) calculations, opens up
                      new pathways toward the realization of spintronic devices
                      exploiting such novel exotic electronic and magnetic
                      states.},
