Thomas Jonathan Wooler (1786 – 29 October 1853) was a British publisher active in the Radical movement of early 19th century Britain, best known for his satirical journal The Black Dwarf.
His interest in legal matters led him to write and publish the pamphlet An Appeal to the Citizens of London against the Packing of Special Juries in 1817.
In 1819, he joined the campaign to elect Sir Charles Wolseley to represent Birmingham in the House of Commons.
For a while, he edited the British Gazette, but, after the Reform Act 1832 was passed, he gave up politics to become a lawyer, though Lincoln's Inn refused to admit him as a student in 1825.
He then became a prisoners' advocate at the police-courts, and wrote books and pamphlets on the British legal system, including Every Man his Own Lawyer in 1845.
