In [[zoological nomenclature]], a '''subphylum''' is a [[taxonomic rank]] below the rank of [[phylum]].

The taxonomic rank of "[[subdivision (rank)|subdivision]]" in [[fungi]] and [[plant taxonomy]] is equivalent to "subphylum" in zoological taxonomy. Some plant taxonomists have also used the rank of subphylum, for instance [[monocotyledons]] as a subphylum of phylum [[Angiospermae]] and [[vertebrates]] as a subphylum of phylum [[Chordata]].{{sfn|Hutchinson|1973}}

== Taxonomic rank ==
Subphylum is:
#subordinate to the [[phylum]] 
#superordinate to the '''infraphylum''', which is in turn superordinate to '''parvphylum'''.<ref>{{Cite journal |last=Cavalier-Smith |first=Thomas |date=2016-10-01 |title=Higher classification and phylogeny of Euglenozoa |url=https://www.sciencedirect.com/science/article/pii/S0932473916300839?via=ihub |journal=European Journal of Protistology |volume=56 |pages=250–276 |doi=10.1016/j.ejop.2016.09.003 |issn=0932-4739|doi-access=free }}</ref>

Where convenient, subphyla in turn can be divided into '''infraphyla'''; in turn such an '''infraphylum''' also would be superordinate to any classes or superclasses in the [[hierarchy]].

== Examples ==
Not all fauna phyla are divided into subphyla. Those that are include: 
*[[Arthropod]]a: divided into subphyla [[Trilobitomorpha]], [[Chelicerata]], [[Myriapoda]], and [[Hexapoda]]
*[[Brachiopoda]]: divided into subphyla [[Linguliformea]], [[Craniformea]] and [[Rhynchonelliformea]]
*[[Chordata]]: divided into [[Tunicate|Tunicata]], [[Lancelet|Cephalochordata]], and its largest subphylum [[Vertebrata]]

Examples of '''infraphyla''' include the [[Mycetozoa]], the [[Gnathostomata]] and the [[Agnatha]].
