James Harrington (or Harington) (3 January 1611 – 11 September 1677) was an English political theorist of classical republicanism. He is best known for his controversial publication The Commonwealth of Oceana (1656). This work was an exposition of an ideal constitution, a utopia, designed to facilitate the development of the English republic established after the regicide, the execution of Charles I in 1649.
