A railway wheel that is capable of suppressing the propagation of cracks is provided. A railway wheel according to the present disclosure includes a hub part, a rim part including a tread and a flange, and a web part. In the railway wheel, in an outer layer of the rim part that includes the tread, an elastic limit σ0 is 430 MPa or more, an initial kinematic hardening coefficient C is 130 GPa or more, and a kinematic hardening coefficient reduction ratio γ is 400 or less. The initial kinematic hardening coefficient C and the kinematic hardening coefficient reduction ratio γ satisfy Formula (1).[Expression1]470≤Cγ{1-exp(-0.007γ)}(1)
