Superspecies is a group of at least two more or less distinctive species with approximately parapatric distributions. Not all species complexes, whether cryptices or ring species are superspecies, and vice versa, but many are. A superspecies consisting of two sister species is called a "species pair".

Examples include:

* Puffinus puffinus group of shearwaters – not a superspecies, but the P. yelkouan group formerly contained therein is indeed one.
* Phylloscopus collybita group of leaf warblers
* Tapaculos
* The genus Citrus, which despite its official classification as a genus retains complete interbreedability.
