A bicycle sprocket includes a base body, a first sprocket tooth and a shifting initiation tooth. The first sprocket tooth includes a drive surface including a drive surface side tooth tip end portion, a non-drive surface including a non-drive surface side tooth tip end portion and a tooth tip portion connecting the drive surface side tooth tip end portion and the non-drive surface side tooth tip end portion. The non-drive surface extends circumferentially with respect to the rotational center axis from the non-drive surface side tooth tip end portion toward a first surface. The tooth tip portion extends circumferentially in a first direction between the drive surface side tooth tip end portion and the non-drive surface side tooth tip end portion. The non-drive surface extends circumferentially from the non-drive surface side tooth tip end portion in a second direction that is inclined with respect to the first direction.
