A rotor (3) for a hover-capable aircraft is described, comprising: a hub (5) rotatable about an axis (A) and, in turn, comprising a plurality of blades (9); a mast (6) connectable to a drive member of the aircraft (1) and operatively connected to the hub (5) to drive the hub (5) in rotation about the axis (A); and damping means (15) for damping vibrations transmitted to the mast (6), which comprise a mass (17) designed to oscillate in a plane transversal to the axis (A) so as to contain flexural vibrations of the mast (6) generated by rotation of the blades (9); the damping means (15) also comprise elastic means (30) having a desired stiffness along the axis (A) and operatively connected to the mass (17) to contain vibration of the mast (6) along the axis (A) .
