The Irish Gaelic form of Queene and MacQueeney means "pleasant".

The surnames are commonly found in Counties Clare and Roscommon.

Other variants of the name include Queen, Mulqueeney and Maqueeney.

The Scottish form of Macqueen or Macsweyns is said to originate from several sources; from the Gaelic Suibhne meaning "going well", or MacCuinn, "son of Conn", or from the Norse, Sweyn.

The Macqueens were of Hebridean and West Highland origin, and appear to have been originally associated with Clan Donald.
