Christopher Plunkett, 8th Baron of Dunsany (died 1603) was an Irish nobleman.
His date of birth is unknown but he was born by 1572, and his future marriage to another of his grandfather's daughters was pledged in that year.
[1]: 30 [2] Plunkett was allegedly involved in the Babington Plot, involving an attempt to free Mary Queen of Scots, and which led to treason charges against her, in 1586, and fled Britain on its discovery.
Around 1592 he spent some time in debtors' prison over a sum of 100 pounds, a matter his father complained of to Lord Burghley.
He was buried at Dunsany and his widow retired to Castleknock, nearer Dublin.
