Clayton Mordaunt Cracherode (1730–1799) was an English book and old master print collector, and a major benefactor of the British Museum.
His father, Colonel Mordaunt Cracherode, later a general, had command of the marines in George Anson's voyage round the world; his mother was Mary, daughter of Thomas Morice, paymaster of the British forces in Portugal, and sister of William Morice, high bailiff of Westminster, who married Atterbury's eldest daughter. Clayton Cracherode was born at Taplow, Buckinghamshire, on 23 June 1730, and educated at Westminster School from 1742, and Christ Church, Oxford, from 1746; "Mr C was perhaps the most amiable man that ever went from Westminster to Christ Church", says his obituary, rather cryptically. He took the degree of B.A. on 4 May 1750, and that of M.A. on 5 April 1763, retaining his Studentship at Christ Church until his death.
Cracherode took Anglican orders, and for some time held the curacy of Binsey, near Oxford, but his church career went no further. On the death of his father in 1773 he inherited a fortune. He was both a Fellow of the Royal Society and a Fellow of the Royal Society of Arts, and a member of the Society of Dilettanti, and in 1784 he was elected a trustee of the British Museum. He died at Queen Square, Westminster, on 5 April 1799, and was buried on 13 April near his mother, in the east cloister of Westminster Abbey.
According to his obituary in The Gentleman's Magazine (almost the only source for details on his personality and life beyond his collecting), Cracherode had never ridden a horse, which was considered remarkable for someone of his class at the time, and in contrast to his father "The greatest journey of his life was from London to Oxford".
