An electric portal axle (1) for electrically driving a motor vehicle has a housing (28), a single electric machine (2) and two spur gear stages (13, 14) for driving two wheels of the axle. A shiftable transmission (5) is downstream of the electric machine (2) and is embodied as a planetary gear mechanism with a freewheel (6) and a differential (7). The portal axle (1) has a shifting mechanism (23) for shifting two gear stages of the portal axle (1). In a first gear stage, a ring gear (9) of the transmission (5) and a clutch body (27) that is fixed to the housing are connected, and a clutch (29) between the ring gear (9) and a planetary carrier (11) of the transmission (5) is opened. In a second gear stage the ring gear (9) and the clutch body (27) are disconnected and the clutch (29) is closed.
