Mein is a German surname with multiple etymological origins.

The personal name itself traces back to Old German forms, such as Meine, which originally occurred as a Frisian short form of longer names like Meinolf or Meinhard.Another possible origin, noted for the German surname, is from the adjective gemein (or mein in some dialects), meaning "mean, nasty" — possibly a nickname for someone with unpleasant characteristics. In the Dutch context, the name may also be a variant of Main, Mains, or the personal name Maino.The surname Mein is also found in Scotland as a variant of Main, which itself derives from magan "strength" or from a place name. According to the United States Census (2010), Mein is the 37,076th most common surname, reported predominantly among White individuals.
