The invention relates to a single-motor five-gear transmission electric drive axle system and a vehicle. The single-motor five-gear transmission electric drive axle system comprises a motor, a first gear shifting mechanism, a second gear shifting mechanism, a planet row assembly and three transmission gear sets. The planet row assembly comprises a sun gear, a planet gear, a planet carrier and a gear ring; the three transmission gear sets comprise a first driving gear, a first driven gear, a second driving gear, a second driven gear and a third driven gear; the motor is connected with the input shaft, and the input shaft is meshed with the normally-meshed intermediate shaft. The first driving gear and the second driving gear are sequentially arranged on the normally engaged intermediate shaft, and the first gear shifting mechanism is arranged between the first driving gear and the second driving gear; the first driven gear and the second driven gear are fixedly arranged on the sun wheel shaft, the sun wheel shaft is sleeved with the third driven gear in an empty mode, and the second gear shifting mechanism is arranged between the third driven gear and the planet row assembly; five transmission gears are formed through cooperation of the first gear shifting mechanism and the second gear shifting mechanism.
