William Delafield Arnold was a British author and colonial administrator.

He was the fourth son of Thomas Arnold, the headmaster of Rugby School. His older brothers included the poet and critic Matthew Arnold and the literary scholar Tom Arnold. William served as an educational administrator in Punjab, in British India. In 1853, William published a novel of Anglo-Indian life, Oakfield; or, Fellowship in the East. William died aged thirty-one, at Gibraltar, on his way home from India. Matthew Arnold's poem "A Southern Night" mourns his early death. William's orphaned children were adopted by his sister Jane Martha and her husband William Edward Forster.

His eldest son Edward Penrose Arnold-Forster (1851 – 19 January 1927), was a manufacturer in Yorkshire and deputy lieutenant for the West Riding. Another son Hugh Oakeley Arnold-Forster became a Cabinet minister in the Balfour government.

Not long after his father's death in 1842, William, a student at Rugby School, was involved in the writing of the official rules of rugby that are still in effect today: "Rugby Rules were written on August 28, 1845 by three students, William Delafield Arnold, WW Shirley and Frederick Hutchins"
