A bicycle sprocket comprises a sprocket body and a chain engagement structure. The chain engagement structure includes a plurality of sprocket teeth. The plurality of sprocket teeth include at least one first tooth and at least one second tooth. The at least one first tooth has a first tooth top extending non-parallel to a sprocket-plane perpendicular to a rotational center axis when viewed from a radial direction of the bicycle sprocket. The at least one first tooth has a first axial chain-engagement width that is larger than an inner link space defined between a pair of inner link plates of a bicycle chain and smaller than an outer link space defined between a pair of outer link plates of the bicycle chain. The at least one second tooth has a second axial chain-engagement width that is smaller than the inner link space.
