An in-vehicle update device acquires an update program transmitted from an external server located outside a vehicle, and updates a program for an in-vehicle control device. The in-vehicle update device includes a storage unit and a control unit, and the storage unit is configured to store the update program, and the control unit is configured to control transmission of the update program to an update target in-vehicle control device. When acquiring the update program from the external server, the control unit transmits saved data stored in the storage unit to the external server, or to a non-update target in-vehicle control device other than the update target in-vehicle control device, based on the data type of the saved data. The control unit stores at least part of the update program acquired from the external server in an area of the storage unit in which the transmitted saved data was stored.
