Thomas Crofton Croker (15 January 1798 – 8 August 1854) was an Irish antiquary, born at Cork. For some years, he held a position in the Admiralty, where his distant relative, John Wilson Croker, was his superior.
Croker devoted himself largely to the collection of ancient Irish poetry and Irish folklore. He assisted in founding the Percy Society and the Camden Society. He and his wife’s testi-monies about funereal customs, particularly the tradition of keening the deceased are among the earlist and most significant contributions to the understanding of the Irish language lament and the accompanying traditions. His work South of Ireland went six editions, it was translated into German by the Brothers Grimm.
Croker died in 1854 and is buried in Brompton Cemetery, London.
