Stephen Coleridge (1854–1936) was a UK author, barrister, opponent of vivisection and co-founder of the National Society for the Prevention of Cruelty to Children.
Stephen Coleridge was the second son of John Duke Coleridge, Lord Chief Justice of England, and Jane Fortescue Seymour, an accomplished artist. His grandfather was nephew to the famous poet Samuel Taylor Coleridge. He was educated at Bradfield College.
In 1903, in the Brown Dog affair, Coleridge accused William Bayliss of the Department of Physiology at University College London of breaking two laws in his handling of a dog which was killed after vivisection. Bayliss sued for libel and was awarded damages of £2,000.
