Kilkea (Irish: Cill Chá)[1] is a village and civil parish in County Kildare, Ireland, about 75 km (47 mi) from Dublin, and 15 km (9.3 mi) from the town of Carlow.

The R418 regional road from Athy to Tullow passes through the village.

Formerly the land of the Ó Tuathails (O'Toole), after the Norman invasion, Sir Walter de Riddlesford built a motte and bailey castle there about 1180.

Walter de Riddlesford's granddaughter, Emmeline Longespee, married Maurice FitzGerald, 3rd Lord of Offaly in 1273, and so the land passed to the Geraldine Earls of Kildare.

Its importance as a town diminished after the rebellion of "Silken Thomas", the 10th Earl of Kildare, in 1534.
