A bicycle sprocket comprises a sprocket body and a plurality of chain-driving teeth. The sprocket body includes a radially outer periphery and an axial center plane. The plurality of chain-driving teeth include at least one noise-reduction tooth. The at least one noise-reduction tooth comprises a downstream circumferential surface, an upstream circumferential surface, and a first axial surface. The first axial surface is provided between the downstream circumferential surface and the upstream circumferential surface to face in an axial direction parallel to a rotational center axis. The first axial surface includes an inclined surface inclined relative to an axial center plane so that an axial width of the at least one noise-reduction tooth decreases from one of the upstream circumferential surface and the downstream circumferential surface to the other of the upstream circumferential surface and the downstream circumferential surface.
