The Centre for Social Justice (CSJ) is an independent[1] centre-right[2] think tank based in the United Kingdom, co-founded in 2004 by Iain Duncan Smith, Tim Montgomerie, and Philippa Stroud.

[4] While the think-tank states it is politically independent, it was labelled one of the most influential on the British Conservative Party under the leadership of David Cameron.

[6] It has also produced well-publicised reports on gang culture,[7] modern slavery,[8] addiction,[9] family breakdown,[10] and educational failure.

[12] The CSJ has also played important roles in the design and development of Universal Credit and in championing the introduction of the Modern Slavery Act 2015.

The CSJ also has an alliance of "front line poverty fighting charities" and runs an annual Centre for Social Justice Awards ceremony celebrating some of the best voluntary and non-profit organisations in the UK.
