William Lovett (1800 - 1877) was a British activist who was a leader of the political movement Chartism as well being as one of the leading London-based Artisan Radicals of his generation.
A proponent of the idea that political rights could be garnered through political pressure and non-violent agitation, Lovett retired from more overt forms of political activity after a year of imprisonment on the political charge of seditious libel in 1839-1840, and subsequently devoted himself to the National Association for Promoting the Political and Social Improvement of the People, desiring to improve the lives of the poor workers and their children by means of a Chartist educational programme put into practice.
