A body reinforcement structure for a sliding door and a vehicle. The body reinforcement structure for a sliding door includes an A-pillar, a B-pillar, a sliding door upper guide groove assembly, and a joint connector. The joint connector is provided with a first connection portion, a second connection portion, and a third connection portion, wherein the first connection portion is connected to the sliding door upper guide groove assembly, the second connection portion is connected to the A-pillar, and the third connection portion is connected to the B-pillar. Utilizing the joint connector, the continuity between the A-pillar, the B-pillar, and the vehicle's roof side beam is improved. Since the sliding door upper guide groove assembly does not overly restrict the size of the connection structure, a firm connection structure between the A-pillar, the B-pillar, and the vehicle body roof can be formed; at the same time, since the vehicle's roof side beam no longer needs to accommodate the connection structure of the A-pillar and the B-pillar, a closed structure can be formed so that the sliding door upper guide groove assembly is enclosed within the roof side beam; thereby greatly improving the structural strength of the vehicle body and improving the scores for side impact and offset impact.
