Simon Wilkin (27 July 1790, in Costessey − 1862, in London) was an English publisher, literary scholar and naturalist whose main interest was entomology.
When his father died Wilkin moved to Norwich to live with his guardian, Joseph Kinghorn, who educated him.
Wilkin lost his inherited wealth in 1811 when the paper mill in which he was a partner failed, and in 1832 his guardian's death was another financial disaster.
Bankruptcy forced the sale of his insect collection to the Zoological Society of London.
He published the work of Harriet Martineau, Amelia Opie, George Borrow, and William Taylor.
