A travel direction estimation device mounted on a vehicle including a position detector and an angular velocity detector to estimate a travel direction of the vehicle includes: a first angle processor calculating a first angle based on a change of a position of the vehicle being detected in the position detector and updated at a predetermined time interval, a second angle processor calculating a second angle based on a rotational angular velocity of the vehicle being detected in the angular velocity detector and a detection interval of the position of the vehicle in the position detector, and a travel direction processor calculating the travel direction of the vehicle based on the first angle and the second angle. The travel direction estimation device can estimate a travel direction of a vehicle with a high degree of accuracy.
