Courtney Stanhope Kenny (18 March 1847 – 18 March 1930) was a British jurist, academic and Liberal politician. He sat in the House of Commons from 1885 to 1888, and was later Downing Professor of the Laws of England at Downing College, University of Cambridge. He is buried with his family in the Parish of the Ascension Burial Ground in Cambridge.^[1]

Kenny was born on the Wirral, the son of William Fenton Kenny J.P. of Halifax and Ripon and his wife Agnes Ralph, daughter of John Rhodes Ralph J.P. of Halifax.^[2] He was educated at the Heath and Hipperholme grammar schools and joined a firm of solicitors in 1863. In 1869 he became a partner but decided to leave and pursue a university education, entering Downing College, Cambridge in 1871. His career at university was particularly brilliant; in 1872 he was awarded a scholarship, in 1874 he was senior in the law and history tripos, won the Winchester Reading Prize, and was elected president of the union. In 1875, he won the chancellor's medal for legal studies.^[3]

Kenny was elected a fellow of Downing College in 1875 and was appointed to a lecturership in law and moral science. In three successive years, 1877, 1878, 1879, he submitted an essay which won him thrice the Yorke Prize; the essays were on the history of the law of primogeniture (jointly with Perceval Maitland Laurence), the law relating to married women's property, and the law of charities.

In 1881 Kenny was called to the bar at Lincoln's Inn and joined the south-eastern circuit.

At the 1885 general election Kenny was elected Member of Parliament (MP) for the Barnsley division of Yorkshire,^[4] and at the general election of June 1886 he was again returned as a Liberal.^[5] While in parliament he introduced bills for the abolition of primogeniture and for the amendment of the law relating to blasphemy, which demanded the repeal of the laws restricting the expression of religious opinion.

In 1888 Kenny became university reader of English law at Cambridge University, and resigned from parliament^[6] to concentrate on work at the university. In 1907 he was elected to replace the recently deceased Frederic William Maitland as Downing Professor of the Laws of England, a position he held until his retirement in 1918.^[7] He died in Cambridge aged 83. Two student residence buildings at Downing College are named in his honour.
