An automatic homing rotary hinge, which includes a pivotal rod, a spring slipped onto the pivotal rod, an assembly board, and a friction portion. The friction portion has a spacer, a baffle, a push gasket, and a skidproof gasket, which are assembled on the pivotal rod in order. Static balance is achieved between a torsion of the spring, the weight of an object and an elastic pressing force and a friction force of the friction portion to arbitrarily position the included angle between two objects. The spring is used to restore the original included angle between the two objects.
