The Equality Trust is a campaigning organisation founded in 2009 by Bill Kerry, Richard G. Wilkinson and Kate Pickett after the publication of Wikinson and Pickett's book The Spirit Level: Why More Equal Societies Almost Always Do Better. It is dedicated to reducing income inequality in the UK. It has an office in Victoria Park Square, London. Its main funders are the Network for Social Change and the Joseph Rowntree Charitable Trust. It has established local groups across Britain and a network of international equality groups.
The Trust ran a campaign for greater equality in the lead up to the United Kingdom general election, 2010.
It argues that there is a strong association between low economic growth and inequality.
The Trust was cited by Caroline Lucas as demonstrating "a clear and demonstrable correlation between drug misuse and inequality" and that drug abuse is more common in more unequal countries such as the UK in her campaign for review of the Misuse of Drugs Act 1971.
