Sweeney (name)

Sweeney is a surname that, though closely associated with Ireland, is of Scottish origin, derived from the Gaelic Mac Suibhne meaning "son of Suibhne". The Gaelic personal name was originally a byname meaning "pleasant" or "well-disposed". The Gaelic personal name was also used an equivalent to the unrelated Old Norse personal name Sveinn, meaning "boy", "servant".

In the United States, the surname Sweeney can also be an Americanization of the French surname Choinière. This French surname is derived from choin, meaning white, and probably originated as an occupational name for a baker.
