Doomsday Preppers is an American reality television series that aired on the National Geographic Channel from 2012 to 2014. The program profiles various survivalists, or "preppers", who are preparing to survive the various circumstances that may cause the end of civilization, including economic collapse, societal collapse, and electromagnetic pulse. The quality of their preparations is graded by the consulting company Practical Preppers, who provide analysis and recommendations for improvements.

Survivalism is a social movement of individuals or groups who proactively prepare for emergencies, such as natural disasters, and other disasters causing disruption to social order caused by political or economic crises. Preparations may anticipate short-term scenarios or long-term, on scales ranging from personal adversity, to local disruption of services, to international or global catastrophe. There is no bright line dividing general emergency preparedness from prepping in the form of survivalism, but a qualitative distinction is often recognized whereby preppers/survivalists prepare especially extensively because they have higher estimations of the risk of catastrophes happening. Nonetheless, prepping can be as limited as preparing for a personal emergency, or it can be as extensive as a personal identity or collective identity with a devoted lifestyle.
