Jesus Camp is a 2006 American documentary film directed by Rachel Grady and Heidi Ewing about a charismatic Christian summer camp, where children spend their summers being taught that they have "prophetic gifts" and can "take back America for Christ". According to the distributor, it "doesn't come with any prepackaged point of view" and attempts to be "an honest and impartial depiction of one faction of the evangelical Christian community".
