- A surname.
Borrowed from German Low German Butt, from Middle Low German but, butte. Cognate with Dutch bot and with English butt, in all senses. Apparently this word had the primitive meaning of being a stump, i. e. being flattened by reason of beating, whereby the root might be identified with the one of English beat and German bossen, bosseln.

- lefteye flounder (fish of the family Bothidae)
