The invention relates to the technical field of vehicles, and discloses a coaxial electric drive system and a vehicle. The coaxial electric drive system comprises a motor, a speed reducer, a differential mechanism and a disconnecting device, wherein the motor comprises a first half shaft and a second half shaft which are coaxially arranged; the speed reducer is arranged in a speed reducer shell and comprises a sun gear, a first planet gear, a second planet gear and a gear ring, the gear ring is arranged on the speed reducer shell, and the first planet gear and the second planet gear are rotationally arranged on the differential shell; the differential mechanism is at least partially located between the second planet wheel and the first half shaft; and a disconnecting device is arranged at the end, away from the second half shaft, of the first half shaft and can selectively connect or disconnect the first half shaft and the hub. The planet wheel shaft of the speed reducer is rotationally arranged on the differential mechanism shell, the differential mechanism is partially located between the second planet wheel and the first half shaft, the structure is compact, the integration degree is high, the disconnecting device can achieve switching of four-wheel drive or hybrid power of a vehicle, and more energy is saved and emission is reduced.
