Sir William Richard Gowers (; 20 March 1845 – 4 May 1915) was a British neurologist, described by Macdonald Critchley in 1949 as "probably the greatest clinical neurologist of all time".
He practised at the National Hospital for the Paralysed and Epileptics, Queen Square, London (now the National Hospital for Neurology and Neurosurgery) from 1870–1910, ran a consultancy from his home in Queen Anne Street, W1, and lectured at University College Hospital.
He published extensively, but is probably best remembered for his two-volume Manual of Diseases of the Nervous System (1886, 1888), affectionately referred to at Queen Square as the Bible of Neurology.
