The Tonkin weasel or Vietnamese mountain weasel (Mustela tonkinensis) is a species of weasel described by Björkegren in 1941. It is known only from a singular specimen collected from an undisclosed location in Northern Vietnam. Originally believed to be a form of either the least weasel or the yellow-bellied weasel, the species was distinguished as a separate variety on the basis of skull differences by Groves in 2007.
