A vehicle door structure includes: a door body that includes an inner panel and an outer panel and that has a space between the inner panel and the outer panel; an acceleration detector that is arranged in the space; a support portion that supports the acceleration detector on the door body so that a direction of sensitivity of the acceleration detector differs from a direction in which the door body is closed; and a sensitivity direction changing portion that changes a position in which the acceleration detector is supported by the support portion so that the direction of sensitivity of the acceleration detector approaches a direction in which the inner panel faces the outer panel as the outer panel is relatively displaced toward the inner panel.
