Lyonel D'Arcy Hildyard (5 February 1861 – 22 April 1931) played first-class cricket for Somerset from 1882 to 1883, for Lancashire in 1884 and 1885, and for Oxford University from 1884 to 1887. He was born at Bury, then in Lancashire, and died at Rowley, near Hull, Yorkshire. While Hildyard won a third Blue in 1886, he was not successful in any of his matches for Oxford that season, and his first-class cricket career ended after a few matches in the 1887 season. He did not play for Lancashire after 1885.
