Tullyhaw () (which means 'The Territory of Eochaidh', an ancestor of the McGoverns, who lived ) is a Barony in County Cavan in the Republic of Ireland. The area has been in constant occupation since pre-4000 BC. Located in the northwest of the county, it has been referred to as Cavan's panhandle.

The last one, Tullyhaw, encompassed the mountains bordering on O'Rourke's country, and was left subject to the ancient tenures and exactions of their Irish lord.
