A foreign substance removal apparatus for a gas turbine includes a combustor casing having a first cooling air passage formed in a tangential direction of a combustor in a gas turbine in order to move cooling air into the combustor, a first foreign substance collection unit disposed on a flow path in the first cooling air passage in order to primarily filter foreign substances contained in the cooling air, a second cooling air passage extending radially toward a turbine blade in a circumferential direction of a torque tube located in the combustor, and a second foreign substance collection unit disposed on a flow path in the second cooling air passage and communicating with the second cooling air passage to secondarily filter foreign substances contained in the cooling air introduced through the first cooling air passage.
