'''''Yokenella''''' is a genus of bacteria of the family Enterobacteriaceae. ''Yokenella'' are Gram-negative, motile, rod-shaped bacteria. Strains of bacteria forming this genus were originally isolated from clinical samples, from the boxelder bug,<ref>{{cite journal|last=Kosako|first=Y|author2=Sakazaki, R |author3=Yoshizaki, E |title=Yokenella regensburgei gen. nov., sp. nov.: a new genus and species in the family Enterobacteriaceae.|journal=Japanese Journal of Medical Science & Biology|date=June 1984|volume=37|issue=3|pages=117–24|doi=10.7883/yoken1952.37.117|pmid=6503024|doi-access=free}}</ref> and from alligators.<ref>{{Cite journal |last1=Balamayooran |first1=Gayathriy |last2=Cooper |first2=Clark |last3=Paul |first3=Narayan C. |last4=Ferro |first4=Pamela J. |last5=Rice |first5=Laura |last6=Gomez |first6=Gabriel |last7=Díaz-Delgado |first7=Josué |title=Yokenella regensburgei, a novel pathogen in farmed American alligators |journal=Veterinary Pathology |date=2022 |volume=59 |issue=3 |pages=476–481 |doi=10.1177/03009858211069165 |issn=1544-2217 |pmid=35001744|s2cid=245834582 }}</ref>

There is only one species in this genus: ''Yokenella regensburgei''.<ref>[https://lpsn.dsmz.de/genus/yokenella LPSN] LSPN bacterio.net</ref>

''Yokenella'' is not an important pathogen, but it has been found in sporadic cases of finger osteitis,<ref>{{Cite journal |last1=Denes |first1=Eric |last2=Alain |first2=Jérome |last3=Lenoir |first3=Isabelle |title=Finger osteitis due to Yokenella regensburgei in an immunocompetent patient |journal=Infectious Diseases Now |date=2022 |volume=52 |issue=3 |pages=177–178 |doi=10.1016/j.idnow.2021.11.004 |issn=2666-9919 |pmid=34838773|s2cid=263490589 }}</ref> necrotizing fasciitis,<ref>{{Cite journal |last1=Wright |first1=William F. |last2=Utz |first2=Jena L. |last3=Bruckhart |first3=Christina |last4=Baghli |first4=Salim |last5=Janda |first5=J.
