An electric vehicle drive unit includes: first and second traveling motors that include first and second rotors, respectively; and a first planetary gear mechanism that includes first to third rotation element, The first rotation element is rotatably coupled to the first rotor. The second rotation element is rotatably coupled to the second rotor via a connection portion. The third rotation element is coupled to an output shaft coupled to a drive wheel side. Rotary axes in the first planetary gear mechanism, the first traveling motor and the second traveling motor are coaxially arranged. The electric vehicle drive unit further includes a clutch that disconnectably connects any two rotation elements among the first to third rotation elements to switch the two rotation elements to a directly coupled state at the time of connection.
