A hinge assembly for a refrigerator door improves productivity and reduces a manufacturing cost by improving a structure of a hinge assembly installed between a refrigerator main body and a door, and improves an appearance by using one hinge assembly for one door so as to coincide moving axes and thus positioning an opened door to be horizontal to the main body. To this end, the hinge assembly includes a shaft having both ends fixed to one side of a door that can be opened and closed, the door being installed at a refrigerator main body; a pair of fixed cams integrally formed at the shaft and transmitting a rotary force when the door is opened and closed; a pair of moving cams linearly reciprocating by contacting with surfaces of the fixed cams in a cam type to allow the door to remain in an opened state when the door is opened to at least a predetermined angle and to return the door to a closed state when the door is at an angle less than the predetermined angle; a housing coupled to the moving cam and fixed to the refrigerator main body; and a spring installed between the moving cams and providing an elastic force.
