We observed the de Haas-Van Alphen oscillation in the heavy fermion compound CeIrIn5. The topology of the Fermi surface is found to be nearly cylindrical, reflecting the unique tetragonal structure. Observed branches are well explained by the 4f-itinerant band model. The cyclotron masses of 20-30m0 are one order larger than the corresponding band masses.
