The Joshua Project is a Christian organization based in Colorado Springs, United States, which seeks to coordinate the work of missionary organizations to track the ethnic groups of the world with the fewest followers of evangelical Christianity. To do so, it maintains ethnologic data to support Christian missions. It also tracks the evangelism efforts among 17,000 people groups worldwide — a people group being "the largest group within which the Gospel can spread as a church planting movement," according to the project's website — to identify people groups as of yet unreached by Christian evangelism.
