There is provided a fusion protein comprising albumin and retinol-binding protein, which can be used for preventing or treating fibrotic diseases. The fusion protein, in which albumin and a retinol-binding protein (RBP) are bound together, induces the formation of cytoplasmic lipid droplets in stellate cells and returns the shape of activated stellate cells to the previous shape thereof before activation. Therefore, the fusion protein can be effectively used in preventing or treating fibrotic diseases occurring in the liver, pancreas, lungs, or other organs.
