The invention discloses a near-zero stiffness supporting device for zero-gravity environment simulation, which belongs to the field of gravity simulation test devices, and comprises a near-zero stiffness supporting assembly and a motion following assembly which are mutually independent, and the near-zero stiffness supporting assembly and the motion following assembly are connected up and down to form a series connection structure. The near-zero rigidity supporting assembly comprises a top plate, a bottom plate, a passive supporting unit and a linear actuator, the passive supporting unit and the linear actuator are arranged between the top plate and the bottom plate, the top plate is parallel to the bottom plate, the top plate is used for bearing to-be-simulated load equipment, the bearing capacity of the passive supporting unit is larger than the gravity borne by the to-be-simulated load equipment, and the motion following assembly is connected with the bottom plate. The passive support unit, the linear actua
