The invention discloses a vehicle D column lower connector and a D column, and belongs to the technical field of vehicle D column fixing structures. The vehicle D column lower connector comprises an inner plate, an outer plate and a reinforcing plate. The inner plate and the outer plate are fixedly connected and form a first cavity. The reinforcing plate is located in the first cavity and provided with a second cavity, and an opening of the second cavity faces the outer plate. The two sides, in the first direction, of the reinforcing plate are fixedly connected with the outer plate, the two sides, in the second direction, of the reinforcing plate are located between the inner plate and the outer plate, the reinforcing plate is clamped by the inner plate and the outer plate, and the first direction and the second direction are arranged at an angle. The side, facing the inner plate, of the reinforcing plate is fixedly connected with the inner plate. The vehicle D column lower connector is good in torsional mode and torsional rigidity, meanwhile, the number of parts included by the vehicle D column lower connector is small, the structure is simple, and the production cost of the vehicle D column lower connector can be reduced.
