GMWatch provides the public with the latest news and comment on genetically modified (GMO) foods and crops and their associated pesticides.

GMWatch is an independent organisation that seeks to counter the enormous corporate political power and propaganda of the GMO industry and its supporters. It does this through its website, email lists, Powerbase portal, LobbyWatch, social media (Twitter and Facebook), and other outreach and campaigning activities. GMWatch was founded in 1998 by Jonathan Matthews and its directors and managing editors are Jonathan Matthews and Claire Robinson.

GMWatch gratefully acknowledges donations from individual supporters as well as NGOs, charitable foundations, and trusts. In 2011 institutional funders included Friends of the Earth Europe, Friends of the Earth UK, the Soil Association, and the Courtyard Trust. Between July 2011 and May 2012 a GMWatch editor received payment from the Institute of Responsible Technology (IRT) for editorial support to the IRT's newsletters. In 2012 and 2013 GMWatch received funding from Friends of the Earth Europe, the Isvara Foundation and the Courtyard Trust. In 2014 GMWatch received funding from the Isvara Foundation, Food Democracy Now!, and the Sheepdrove Trust.
