The 2009 G20 London Summit was the second meeting of the G20 heads of government/heads of state, which was held in London on 2 April 2009 at the ExCeL Exhibition Centre to discuss financial markets and the world economy. It followed the first G20 Leaders Summit on Financial Markets and the World Economy, which was held in Washington, D.C. on 14–15 November 2008.Heads of government or heads of state from the G20 attended, with some regional and international organisations also represented. Due to the extended membership it has been referred to as the London Summit.

The policing tactics at the event raised some controversy, particularly over the death of Ian Tomlinson.

It was revealed in June 2013 that the Government Communications Headquarters, an intelligence agency of the British government, had intercepted phone calls and monitored computers used by foreign delegates at the summit. Their actions were sanctioned by the British government and intelligence was passed to British government ministers.

As hosts, the British Treasury produced an extended agenda pamphlet proposing the issues to be addressed at the London Summit. The explicit goal was "to start the process of reform so as to manage globalisation as a force for good in the medium term."

Leaders of the member countries began to prepare for the London Summit months before the effective date, notably with two official meetings dedicated to that preparation, one held in Berlin, Germany, on 22 February 2009 for European leaders, and another in Horsham, Sussex, United Kingdom, on 14 March 2009 for Finance Ministers.

Leaders of the four European Union member countries of the G20, the United Kingdom, Germany, France and Italy along with the two largest European non-members, Spain and the Netherlands, met in Berlin on 22 February 2009 to prepare for the London Summit and to co-ordinate their actions. The meeting was organised at the initiative of German Chancellor Angela Merkel.
