A universal camera supporting jib is disclosed to have a tripod, a base horizontally rotatably fixed on the tripod, first arm and a second arm vertically pivotably fixed on the base and respectively define a long and a short portion. A large and a small four-link mechanisms are respectively formed by means of the long and small portion of the first and second arms. A camera is mounted on an end of one link of the large four-link mechanism, wherein the link is parallel to the second arm. A counter balance weight for balancing the weight of the camera is mounted on an end of one link of the small four-link mechanism, wherein the link is also parallel to the second arm. When the position of the camera is changed the position of the counter balance weight is changed accordingly through the cooperative action between the two four-link mechanisms thereby to balance the weight of the camera.
