To suppress variation of power caused by waste heat recovery engines when waste heat is recovered using a plurality of waste heat recovery engines.
In this waste heat recovery system 10, Stirling engines 100A, 100B recover thermal energy of waste gas Ex discharged from an internal combustion engine 20. The high temperature cylinder 101 of the Stirling engine 100A arranged on a bank 22B1 is arranged between internal combustion engine cylinders 22 represented by #1 and #2, and the low temperature cylinder 102 thereof is arranged between internal combustion engine cylinders 22 represented by #2 and #3. The high temperature cylinder 101 of the Stirling engine 100B arranged on a bank 22B2 is arranged between internal combustion engine cylinders 22 represented by #4 and #5, and the low temperature cylinder 102 thereof is arranged between internal combustion engine cylinders 22 represented by #5 and #6.
