Tonkinense is a Latin adjective meaning "of Tonkin." Tonkin was a historical region in northern Vietnam, corresponding roughly to the area of the Red River Delta. The term "tonkinense" is often used in scientific nomenclature to refer to species or other taxa discovered in or associated with this geographic region. For example, one might find a scientific name such as Species tonkinense, indicating that the species was first described from specimens collected in Tonkin.

The historical significance of Tonkin as a distinct cultural and geographical entity has led to its continued presence in taxonomic classifications.
