Franklin’s Bumblebee is, or perhaps was, one of the most narrowly distributed bumblebee species of the world, it is known only from a small area between the coast and the Sierra-Cascade Mountains in northern California and southern Oregon, USA.

The species was last seen in 2006 at Mt. Ashland in Oregon and is now most likely extinct.
