A dual axis hinge includes: a track seat that extends along a center line, and that has two pairs of inner track grooves and two pairs of outer track grooves; two support mechanisms that are respectively disposed on opposite sides of the center line, that movably engage the inner track grooves and the outer track grooves of the track seat, and that are convertible between a folded state and an unfolded state; and two synchronization mechanisms that are respectively connected to opposite sides of the track seat, and that are configured to move in a synchronous manner such that movements of the support mechanisms relative to the track seat are synchronized.
