Provided is a railway wheel capable of suppressing formation of pro-eutectoid cementite even if the C content is high. A railway wheel according to an embodiment of the present invention has a chemical composition consisting of: in mass%, C: 0.80 to 1.15%; Si: 0.45% or less; Mn: 0.10 to 0.85%; P: 0.050% or less; S: 0.030% or less; Al: 0.120 to 0.650%; N: 0.0030 to 0.0200%; Cr: 0 to 0.25%; and V: 0 to 0.12%, with the balance being Fe and impurities, wherein an amount of pro-eutectoid cementite, which is defined by Formula (1), in a microstructure of the railway wheel is not more than 1.50 pieces/100 µm:Amountofpro-eutectoidcementitepieces/100μm=atotalsumofthenumberofpiecesofpro-eutectoidcementitewhichintersectwithtwodiagonallinesinasquarevisualfieldof200μm×200μm/5.66×100μm
