Thomas Skidmore (August 13, 1790 – August 7, 1832) was an American politician and radical political philosopher. Skidmore is best remembered as the co-founder and leader of the Working Men's Party in New York when it first emerged in the fall of 1829. He was forced out of the organization shortly after its initial electoral campaign by moderate leaders of the party on the grounds of Skidmore's excessive radicalism and unbending personality. Skidmore went on to establish another short-lived political organization in 1830, known as the Agrarian Party.
