William Thompson (1775 – 28 March 1833) was an Irish political and philosophical writer and social reformer, developing from utilitarianism into an early critic of capitalist exploitation whose ideas influenced the cooperative, trade union and Chartist movements as well as Karl Marx. Born into the Anglo-Irish Ascendancy of wealthy landowners and merchants of Cork society, his attempt to will his estate to the cooperative movement after his death sparked a long court case as his family fought successfully to have the will annulled. According to E. T. Craig, this decision to will his estate to the cooperative movement was taken after a visit to the pioneering Ralahine Commune. Marxist James Connolly described him as the "first Irish socialist" and a forerunner to Marx, who cited Thompson in his works as well as being an influence upon Marx's thought.

Ideas An enthusiastic student of the writers and ideas of the Enlightenment, particularly Condorcet, Thompson became a convinced egalitarian and democrat. His support for the French Revolution earned him the label of "Red Republican" from Cork society and his support for advocates of Catholic emancipation in elections further alienated him from the rest of his wealthy Protestant kith and kin. Thompson was greatly impressed by the utilitarianism of Jeremy Bentham, with whom he corresponded and established a friendship, later staying at the English philosopher's house for several months in 1821–22 while visiting London. As well as Bentham, Thompson read and corresponded with other utilitarian contemporaries such as James Mill, and was influenced, both positively and negatively, by William Godwin and Thomas Malthus.
