The invention discloses a frame structure of a light high-maneuverability off-road vehicle. The frame structure comprises a front bumper, a front suspension mounting beam, a cross beam, longitudinal beams, a vehicle body suspension beam, a container supporting structure, a rear suspension mounting beam and a rear bumper; the two longitudinal beams are oppositely arranged in the left-right direction of the vehicle body and comprise a left longitudinal beam and a right longitudinal beam; each longitudinal beam is a box beam formed by tailor-welding two first channel beams along the left-right direction of the vehicle body; each longitudinal beam is provided with an engine mounting hole used for mounting an engine, a transmission mounting hole used for mounting a transmission and a suspensionmounting hole used for mounting a suspension; each longitudinal beam comprises a vehicle front section, a vehicle middle section and a vehicle rear section which are integrally formed in the front-back direction of the vehicle body; each vehicle front section and each vehicle rear section are higher than the corresponding vehicle middle section, so that the longitudinal beams are arranged in thefront-back direction of the vehicle body with two high ends and a low middle. The requirement for high-maneuverability driving of the off-road vehicle is met, the local strength is high, the overall flexibility is good, and the bearing capacity is high.
