Clonmacnowen (Irish: Clann Mhac nEoghain; also Clonmacnoon) is a historical barony in eastern County Galway, Ireland.
Baronies were mainly cadastral rather than administrative units. They acquired modest local taxation and spending functions in the 19th century before being superseded by the Local Government (Ireland) Act 1898.
