The Global Investigative Journalism Network (GIJN) is composed of nonprofit investigative journalism organizations that produce stories, conduct training, provide resources, and encourage the creation of similar nonprofit groups. It was created in 2003 when more than 300 journalists from around the world gathered for the second Global Investigative Journalism Conference in Copenhagen. Since then it has grown to more than 70 member organizations in 35 countries.

Every 18 to 24 months, GIJN holds the Global Investigative Journalism Conference, which has brought together nearly 4,000 journalists from 100 countries since 2001. GIJN member organizations also hold regional conferences, such as the Power Reporting Conference sponsored by the Forum for African Investigative Reporters and Wits University in Johannesburg. The initial global conference was held in Copenhagen in 2001; Other conferences have been held in Copenhagen (2003), Amsterdam (2005), Toronto (2007), Lillehammer (2008), Geneva (2010), and Kiev (2011). The next conference is planned for Rio de Janeiro in October 2013, and is being done in partnership with Abraji, the Brazilian Association of Investigative Journalists, and IPYS, the Lima-based Institute for Press and Society.
