This order comprises four families:

  • Procellariidae (petrels, shearwaters)
  • Hydrobatidae (northern storm petrels)
  • Oceanitidae (southern storm petrels)
  • Diomedeidae (albatrosses)

Genus-level phylogeny of extant Procellariiformes according to the results of Estandía et al. (2021), with the distribution of each family being indicated by the colour-code used throughout this website (see Distribution code). Note that the four genera of Hydrobatidae recognised here may also be united in the broader genus Hydrobates
