A bicycle sprocket comprises a sprocket body and a chain engagement structure. The sprocket body has a rotational center axis, a first side and a second side opposite to the first side in an axial direction parallel to the rotational center axis. The chain engagement structure includes a plurality of sprocket teeth. The plurality of sprocket teeth include a plurality of first teeth and a plurality of second teeth. The plurality of first teeth each include an outer-link supporting surface, an opposite surface, and a first radially outermost tooth-tip. The opposite surface is spaced part from the second outer link plate in a state where the chain engagement structure engages with the bicycle chain. The plurality of second teeth each include a second radially outermost tooth-tip that is offset from the first radially outermost tooth-tip of each of the plurality of first teeth in the axial direction.
