John Ramsay McCulloch (1 March 1789 – 11 November 1864) was a Scottish economist, author and editor, widely regarded as the leader of the Ricardian school of economists after the death of David Ricardo in 1823. He was appointed the first professor of political economy at University College London in 1828. He wrote extensively on economic policy, and was a pioneer in the collection, statistical analysis and publication of economic data.

McCulloch was a co-founder, and one of the first editors, of The Scotsman newspaper, and worked on the Edinburgh Review. He edited the 1828 edition of The Wealth of Nations.
