Ikeathy and Oughterany (Irish: Uí Chéithigh agus Uachtar Fhine) is a barony in County Kildare, Ireland.

Ikeathy takes its name from the Uí Cheithig túath, who claimed descent from Ailill Cétach, a son of the legendary Leinster king Cathair Mór.

Ikeathy and Oughterany is found in northern County Kildare, reaching from Clongowes Wood to the Royal Canal, mostly to the east of the Enfield Blackwater.

Ikeathy and Oughterany was the ancient lands of the Uí Cheithig and the Uachtar Fine.

Around 1300 the barony was held by the Rochfort family, then reverted to the Crown, who regranted it to John Wogan, Justiciar of Ireland.
