James Johnson Battersby (1875–1949) was a British hat manufacturer. He was one of seven brothers, a number of whom worked in the family firm of Battersby Hats which at one time was one of the largest hat manufacturers in Britain. In 1915, he was the last survivor to be rescued after the RMS Lusitania was hit by a German torpedo and sunk. His son was the British fascist James Larratt Battersby.
