The Echlin Baronetcy, of Clonagh in the County of Kildare, was a title in the Baronetage of Ireland. It was created on 17 October 1721 for Sir Henry Echlin, 2nd Baron of the Court of Exchequer (Ireland). He was the great-grandson of the Right Reverend Robert Echlin, Bishop of Down and Connor between 1613 and 1635. The title became dormant on the death of the tenth Baronet in 2007.

Three members of the family sat in the Irish House of Commons: Robert Echlin, eldest son of the first baronet and father of the second baronet; Lieutenant-General Robert Echlin, younger brother of the first baronet; and Charles Echlin, eldest son of John Echlin, the elder brother of the first baronet.

Their main residence was at Kenure House, Rush, County Dublin.
