A floating support structure for an offshore wind turbine, comprises a float intended to be partly immersed and on which a wind turbine mast is intended to be assembled, and a counterweight connected to the float and intended to be immersed under the float. The float comprises a toroid or polygon-shaped main structure with at least five sides, a central tubular structure having a diameter adapted to receive the mast of the wind turbine and comprising a section able to be ballasted in order to adjust the waterline of the float, a first series of horizontal struts distributed about a vertical axis and connecting the main structure to the central structure, and a second series of oblique struts distributed about a vertical axis and connecting the main structure to the central structure at an angle comprised between 15&#xb0; and 60&#xb0; with the horizontal struts.
