James Richard Atkin, Baron Atkin, PC, FBA (28 November 1867 – 25 June 1944), commonly known as Dick Atkin, was an Australian-born British judge, who served as a lord of appeal in ordinary from 1928 until his death in 1944. He is especially remembered as the judge giving the leading judgement in the case of Donoghue v Stevenson in 1932, in which he established the modern law of negligence in the UK, and indirectly in most of the common law world.
