William Henry Benson (1803, probably in Dublin - 27 January 1870) was a civil servant in British India and an amateur malacologist. He made large collections of molluscs and described numerous species from the U.K., India and South Africa. On the return from a trip to Mauritius he brought a couple of living Achatina fulica which he gave to a friend in Calcutta in April 1847 who subsequently released them in a garden at Chowringhee. The species is today a pest in many parts of India.
