* Family: Cricetidae (cricetids, a diverse family of rodents that includes hamsters, voles, and lemmings)
* Subfamily: Cricetinae (cricetines, the subfamily that includes hamsters)
* Genus: Varies depending on the species, but common examples include *Cricetus* (for the European hamster), *Mesocricetus* (for the Syrian hamster), and *Phodopus* (for the dwarf hamsters).
* Species: Again, depends on the specific hamster species, for example, *Cricetus cricetus* (European hamster), *Mesocricetus auratus* (Syrian hamster), or *Phodopus campbelli* (Campbell's dwarf hamster).
Important Note: The scientific classification of hamsters is constantly evolving as new research emerges. There are many different species of hamsters, and their classification can be complex.
