A bicycle sprocket has a rotational center axis. The bicycle sprocket comprises a sprocket body and a chain engagement structure. The sprocket body has an axial width defined in an axial direction parallel to the rotational center axis. The chain engagement structure is arranged on a radially outer periphery of the sprocket body. The chain engagement structure includes at least one shifting facilitation area and a plurality of chain-engaging teeth. The at least one shifting facilitation area is configured to facilitate changing gears. The plurality of chain-engaging teeth include at least two neighboring chain-engaging teeth each including a chain-engaging portion configured to engage with a bicycle chain. The chain-engaging portion has an axial chain-engaging width defined in the axial direction. The axial chain-engaging width is larger than the axial width of the sprocket body.
