Abstract: It is an object of the present invention to provide a technique to make it possible to estimate a travel route even if no destination is set or estimated. A travel route estimation apparatus includes an acquisition unit and a route estimation unit. The acquisition unit acquires an estimated destination which is estimated as a destination of a vehicle, a current position of the vehicle, and a travel history of the vehicle. When the acquisition unit does not acquire the estimated destination, the route estimation unit estimates a travel route which the vehicle travels from the current position, on the basis of the current position and the travel history which are acquired by the acquisition unit.
