In this paper, we study the physical properties of thin accretion disks in static and spherically symmetric multi-polytropic wormhole space-time. Using the Novikov-Thorne model, the electromagnetic flux, temperature distribution, innermost stable circular orbits and radiative efficiency of thin disks are obtained. Comparing the results with traversable wormholes obtained by Morris and Thorne (TWH) and the Schwarzschild solution, we show that thin accretion disks around multi-polytropic wormhole geometry are more luminous and more efficient than the TWH and Schwarzschild black hole.
