Catalyst (later Catalyst Forum) was an independent left wing think tank based in London, United Kingdom, set up in 1998 to promote policies directed to the redistribution of power, wealth and opportunity. Though not aligned to any political party, it was generally sympathetic to the Labour Movement and described itself as "an organisation of the left".
The organisation was founded at the high point of Tony Blair's modernisation of the Labour Party and struggled to attract funding, especially from the trades unions who had originally been expected to be the most sympathetic to its redistributionist platform. Trades unions, concerned at further exclusion from power either by the electorate or the new Labour Party leadership, took a sharp turn away from too deep an association with the Left at this time and only begun in 2005 and 2006 to develop an increased if cautious interest in left-wing thought as a new generation of activist trades union leaders has emerged.
It not only survived the modernisation period but re-emerged strengthened in recent years with a new generation of academics and intellectuals prepared to develop alternative democratic socialist policies. In 2003 Catalyst won the "One To Watch" category at Prospect magazine's annual Think Tank Awards. In 2006 it merged with the Compass organisation (see Compass (think tank)).
