Tireragh (/ˌtɪˈrɛərə/; Irish: Tír Fhiachrach) is a historical barony in Connacht, Ireland. It largely corresponds to the former Gaelic túath of Tír Fhíacrach Múaidhe.

Originally situated solely within the borders of County Sligo, the Local Government (Ireland) Act 1898 altered existing county boundaries, resulting in the traditional baronial lands of Tireragh now falling within the administrative boundaries of both County Sligo and County Mayo.
