The invention concerns a floating support structure (10) for an offshore wind turbine, comprising a float (12) intended to be partially submerged and on which a wind turbine mast is intended to be assembled, and a counterweight linked to the float and intended to be submerged under the float, the float comprising a main structure (18), the shape of which is toroidal or polygonal with at least five sides, a central tubular structure (26) having a diameter suitable for receiving the wind turbine mast and comprising a section suitable for being ballasted in order to adjust the waterline of the float, a first series of horizontal struts (28) distributed around a vertical axis and linking the main structure to the central structure, and a second series of oblique struts (30) distributed around a vertical axis (Y-Y) and linking the main structure to the central structure, forming an angle of between 15° and 60° with the horizontal struts (28).
