'''Cyclophyllidea''' (the '''cyclophyllid cestodes''') is the [[order (biology)|order]] of [[Cestoda|Cestoda (tapeworm)]]. It is the largest and most diverse order of Cestoda (tapeworm), encompassing species that infect all classes of terrestrial [[Tetrapod|tetrapods]] including humans and domesticated animals,<ref>{{Cite journal |last1=Yuan |first1=Hao |last2=Jiang |first2=Jiamei |last3=Jiménez |first3=Francisco Agustín |last4=Hoberg |first4=Eric P. |last5=Cook |first5=Joseph A. |last6=Galbreath |first6=Kurt E. |last7=Li |first7=Chenhong |date=September 2016 |title=Target gene enrichment in the cyclophyllidean cestodes, the most diverse group of tapeworms |url=https://pubmed.ncbi.nlm.nih.gov/27037792/ |journal=Molecular Ecology Resources |volume=16 |issue=5 |pages=1095–1106 |doi=10.1111/1755-0998.12532 |issn=1755-0998 |pmid=27037792}}</ref> and includes species with some of the most severe health impact on wildlife, livestock, and humans.<ref>{{cite journal | pmc=8861457 | date=2022 | last1=Wu | first1=Y.

All have multiple [[proglottid]] "segments", and all have four suckers on their [[scolex|scolices]] (heads), though some may have other structures, as well.  Proglottids of this order have genital openings on one side (except in the <!-- [[family (biology)|family]] --> Dilepididae, which have genital openings on both sides), and a compact yolk gland or [[vitellarium]] posterior to the ovary.

Families include:<ref>{{cite web|url=http://animaldiversity.org/accounts/Cyclophyllidea--Cestoda/classification/|title=Cyclophyllidea|publisher=University of Michigan}}</ref>
* Dipylidiidae, the most important member of which is ''[[Dipylidium caninum]],'' also called the "[[cucumber]] tapeworm" or the "double-pore tapeworm"
* [[Hymenolepididae]],  including the genus ''[[Hymenolepis (flatworm)|Hymenolepis]]'', a human parasite
* [[Taeniidae]], which consists of livestock parasites in the [[genus]] ''[[Taenia (flatworm)|Taenia]]'' and parasites that encyst in humans of the genus ''[[Echinococcus]]''
* [[Anoplocephalidae]], which includes several tapeworms of horses and a genus of tapeworms of ruminants, the ''[[Moniezia]]''
* [[Davaineidae]], which comprises 14 [[genera]], most of which are parasites of [[bird]]s
* [[Acoleidae]], which comprises two genera that parasitize birds
* [[Amabiliidae]], comprising four genera that parasitize aquatic birds
* [[Dilepididae]], comprising 24 or so genera
* [[Diploposthidae]]
* [[Gryporhynchidae]]
