William Lovett was a British activist and leader of the Chartist political movement. He was one of the leading London-based artisan radicals of his generation.

Chartism was a working-class movement for political reform in the United Kingdom that erupted from 1838 to 1857 and was strongest in 1839, 1842 and 1848. It took its name from the People's Charter of 1838 and was a national protest movement, with particular strongholds of support in Northern England, the East Midlands, the Staffordshire Potteries, the Black Country and the South Wales Valleys, where working people depended on single industries and were subject to wild swings in economic activity. Chartism was less strong in places, such as Bristol, that had more diversified economies. The movement was fiercely opposed by government authorities, who finally suppressed it.
