The invention discloses a rock triaxial creep test device, and belongs to the technical field of test equipment. The rock triaxial creep test device comprises a creep shell, a positive pressure assembly and a confining pressure assembly, the creep shell comprises a top frame and a base for bearing a test piece; the confining pressure assembly comprises a bottom ring arranged on the base and a confining pressure side plate arranged between the bottom ring and the top frame, and a confining pressure cavity is formed among the bottom ring, the confining pressure side plate, the top frame and the base; and an oil way hole communicated with the confining pressure cavity is formed in the base and externally connected with a connector. The positive pressure assembly is arranged above the test piece and applies a positive pressure load to the test piece. According to the invention, through cooperation of the components, a load is conveniently applied to a test piece for a creep experiment, and the creep shell can be
