A centrifugal compressor includes a compressor housing accommodating an impeller, and a casing treatment. The compressor housing include an air introduction hole through which air is introduced toward the impeller, an annular portion disposed inside the air introduction hole, and spoke portions. Each of the spoke portions connects an inner circumferential wall surface of the air introduction hole and the annular portion. The casing treatment includes a tubular portion provided on an upstream side of the annular portion in the air introduction hole in an introduction direction of the air, and wing-like portions. Each of the wing-like portions extends from the tubular portion toward a downstream side in the introduction direction of the air.
