The invention relates to an electric axle drive (10) for a motor vehicle axle (16) comprising two vehicle wheels (12, 14), said electric axle drive comprising: an electric machine (18) which has a stator (20) and a rotor (22); and a planetary gear set (26) which, as a drive (34), has a ring gear (30), a planet carrier (32) and a sun gear (28) via which drive torques, which can be provided by the rotor (22), can be introduced into the planetary gear set (26), wherein a first output shaft (36), which can drive a first of the vehicle wheels (12, 14), is connected in a torque-transmitting manner to the ring gear (30) as a first output (38) of the planetary gear set (26). A second output shaft (40), which can drive the second vehicle wheel (14), is connected in a torque-transmitting manner to the planet carrier (32) as a second output (42) of the planetary gear set (26), the outputs (38, 42) of the planetary gear set being capable of dissipating output torques from the planetary gear set (26), which output torques result from the drive torques, in order to drive the vehicle wheels (12, 14).
