John Rickman FRS (22 August 1771 – 11 August 1840) was an English government official and statistician of the early nineteenth century. He was born in Newburn, Northumberland, son of the Rev Thomas Rickman, and educated at Guildford Grammar School, Magdalen Hall, Oxford, and Lincoln College, Oxford. The poet Robert Southey was one of his friends. Rickman became Clerk Assistant in 1820, a post which he held to his death. It is often stated that Rickman was Clerk of the House of Commons: this was never the case.
