Rory Oge O'More (Irish: Ruairí Óg Ó Mórdha; c. 1544 – 30 June 1578) was an Irish noble and chief of the O'More clan. As the Lord of Laois, he rebelled against the Tudors' sixteenth-century conquest of Gaelic Ireland.

O'More is considered the greatest obstacle to Elizabeth I's conquest of the Irish midlands. He was killed by troops led by his loyalist cousin Barnaby Fitzpatrick, 2nd Baron Upper Ossory.
