Arthur Lehman Goodhart KBE, KC (1891-1978) was an academic lawyer and the first American to be the Master of an Oxford College.

He was born in New York and educated at the Hotchkiss School, Yale University and Trinity College, Cambridge. He returned to the United States where he practised law until the first world war. Following the war, he started to pursue an academic career in law, initially at Cambridge University and later at Oxford University where he became a Professor of Jurisprudence and subsequently the Master of University College. He was Editor of the Law Quarterly Review for fifty years.

He was married to Cecily Goodhart (nee Carter) and had three children Sir Phillip Goodhart, Lord William Goodhart and Charles Goodhart (after whom Goodhart's law is named).
