A lubricating oil supply device for a vehicle includes an electric oil pump and an electronic control unit. The electronic control unit is configured to control the electric oil pump, determine whether or not lubricating oil needs to be supplied by the electric oil pump, control a drive duty of the electric oil pump to a first value when the ECU determines that lubricating oil needs to be supplied, and control the drive duty to a second value that is smaller than the first value when the ECU determines that lubricating oil does not need to be supplied. The electronic control unit is configured to perform duty variable control for controlling the drive duty to a third value, which is between the first value and the second value, during a predetermined changeover transition period, in changing over the drive duty from the first value to the second value.
