A bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, and at least one chain-supporting portion. The plurality of sprocket teeth includes at least one first tooth and at least one second tooth. The at least one chain-supporting portion is arranged on the sprocket body to face the bicycle chain in an axial direction parallel to a rotational center axis of the bicycle sprocket without being received within an outer link space and an inner link space in a state where the plurality of sprocket teeth engages with a bicycle chain. The at least one chain-supporting portion is spaced apart from at least one of at least one first tooth and the at least one second tooth in the axial direction.
