Coshma (Irish: Cois Máighe) is a historical barony in southeast County Limerick, 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 They acquired modest local taxation and spending functions in the 19th century before being superseded by the Local Government (Ireland) Act 1898.
