'''Flagellins''' are a family of [[proteins]] present in [[flagellate]]d [[bacteria]]<ref name="UniProt">{{cite web |title=Bacterial flagellin family |url=https://www.uniprot.org/uniprotkb?query=%28family%3A%22bacterial+flagellin+family%22%29 |website=www.uniprot.org}}</ref> which arrange themselves in a hollow cylinder to form the filament in a [[bacterial flagellum]]. Flagellin has a mass on average of about 40,000 [[Atomic mass unit|daltons]].<ref name="MeSH">{{cite web |title=MeSH Browser |url=https://meshb.nlm.nih.gov/record/ui?name=Flagellin |website=meshb.nlm.nih.gov |access-date=29 February 2024}}</ref><ref name="IJMS">{{cite journal |vauthors=Nedeljković M, Sastre DE, Sundberg EJ |title=Bacterial Flagellar Filament: A Supramolecular Multifunctional Nanostructure |journal=Int J Mol Sci |volume=22 |issue=14 |date=July 2021 |page=7521 |pmid=34299141 |pmc=8306008 |doi=10.3390/ijms22147521 |doi-access=free |url=}}</ref> Flagellins are the principal component of bacterial flagella that have a crucial role in [[Bacterial motility#Flagellum|bacterial motility]].

The [[gene]] that encodes for flagellin has a different name in different bacterial species such as ''flaA'' (''[[Helicobacter pylori]]'' for example), ''fliC'', ''fljB''.<ref name="steiner" /><ref name="UniProt"/>
