The Institute for Strategic Dialogue (ISD) is a political advocacy organization founded in 2006 by Sasha Havlicek and George Weidenfeld and headquartered in London, United Kingdom.

ISD's core activities range from traditional research output and policy advice to the facilitation of youth and practitioner networks and the development of counternarrative and technological tools to combat extremism.

[1] More recently, ISD has researched misinformation and disinformation involving climate change,[2] public health,[3] election integrity,[4] and conspiracy networks such as QAnon.

[11] It also works on funded projects with technology companies and organisations such as Google,[12] Microsoft,[13] Meta,[14] and the Global Internet Forum to Counter Terrorism.

[29] By 2012, ISD was working with social media platforms such as YouTube to explore radicalisation online,[30] including research on the use of counternarratives[31] to minimise the impact of extremist recruitment by groups such as ISIS,[32] Al Qaeda,[33] and white supremacists[34] in Europe and North America.
