John Horsefield (18 July 1792 – 6 March 1854) was an English handloom weaver and amateur botanist after whom the daffodil Narcissus 'Horsfieldii' is named. Horsefield had little formal schooling, and acquired most of his botanical knowledge through self-study and involvement in local botanical groups, which provided a venue for working class people to share knowledge, in part by pooling money to purchase books.
