Delta Green is a contemporary era setting for the Call of Cthulhu role-playing game created by Adam Scott Glancy, Dennis Detwiller, and John Scott Tynes, a.k.a. the Delta Green Partnership, of the Seattle gaming house Pagan Publishing. The setting first appeared in a 1992 RPG scenario and revolves around a secretive organization tasked with protecting the United States from paranormal and alien threats. Delta Green combines the classic 1920s Cthulhu Mythos of H.P. Lovecraft with modern conspiracy fiction. In August 2011, Arc Dream Publishing and the Delta Green Partnership announced development of a standalone Delta Green role-playing game. Funding began in 2015 and in 2016 the Agent's Handbook was released followed by the Handler's Guide in 2018. Arc Dream Publishing also made a partnership with Pelgrane Press to release a prequel named The Fall of DELTA GREEN using the Gumshoe System in 2018.

The 2016 edition advances the history to the 2010s. In 2001, the September 11 attacks greatly affects the Intelligence Community, including Delta Green and MAJESTIC-12. Majestic was weakened and destroyed, while Delta Green has been brought back into the government fold, given a budget and official standing, using the War on Terror as a cover to their operation. There's also a group of old guard agents that were opposed to the restructure of Delta Green, preferring to maintain the old conspiracy running, forming their own splinter group known as "The Outlaws", as opposed to the official "Program". The Fall of DELTA GREEN, on the other hand, is a spin-off set during the 1960s. Focusing on Delta Green's operations during
