John George Witt (24 September 1836, Denny Abbey, Waterbeach, Cambridgeshire – 7 February 1906, London) was an English barrister.
He was taught at home by a governess and then attended Eton College, where he was a King's Scholar, 'Keeper of the Wall' and 'Captain of the School,' and founded 'College Pop.'
He went from Eton to King's College, Cambridge, where he was a Fellow from 1859, won the 'Hulsean Prize' in 1860, played football for the university against Oxford, and obtained his B.A.
His books dealt with disparate subjects: the law, the history of Christian doctrine, and (in Three Villages) the local history of villages in which he had successively lived: Waterbeach; Swaffham Prior in Cambridgeshire; and, latterly, Finchampstead in Berkshire.
John George Witt died on 7 February 1906, 'in an omnibus in the Strand, on his way to the Law Courts.'
