The sole exception to this is Herschel Crater, named after William Herschel, the astronomer who discovered Mimas in 1789. That name was chosen before the International Astronomical Union set a guideline for naming geological features on Mimas.

With the exception of Herschel, the craters of Mimas are named after characters in Arthurian legend.
