Provided is an electric vehicle shift control device capable of suppressing the occurrence of busy-shifts. This electric vehicle shift control device is mounted on the electric vehicle which comprises a motor generator (MG) which is the drive source, and an automatic transmission (3) which is connected to the transmission input shaft (6) of the motor generator (MG); this electric vehicle shift control device is provided with a shift controller (21) which performs shift control of the automatic transmission (3) using shift lines provided in advance, wherein the shift controller (21) has, as shift lines, a power consumption-prioritizing shift line configured to prioritize increasing power consumption ratio and a drive-prioritizing shift line configured to prioritize suppressing shift frequency. Further, this electric vehicle shift control device is configured such that after completion of shift control using the power consumption-prioritizing shift line, the drive-prioritizing shift line is used for a prescribed time interval.
