Neoaves is a clade that consists of all modern birds (Neornithes or Aves) with the exception of Paleognathae (ratites and kin) and Galloanserae (ducks, chickens and kin). The early diversification of the various neoavian groups occurred very rapidly, and attempts to resolve their relationships with each other have resulted initially in much controversy.

One hypothesis for the phylogeny of modern birds was presented by Jarvis et al. (2014). The following cladogram illustrates the proposed relationships, with some taxon names following Yury, T. et al. (2013).

Another hypothesis for the phylogeny of modern birds is shown in the following cladogram, based on Prum et al. (2015).
