Ecofascism is a term used to describe individuals and groups which combine environmentalism with fascism.

Philosopher André Gorz characterized eco-fascism as hypothetical forms of totalitarianism based on an ecological orientation of politics. Similar definitions have been used by others in older academic literature in accusations of ecofascism of "environmental fascism". However, since the 2010s, a number of individuals and groups have emerged that either self-identify as "ecofascist" or have been labelled as "ecofascist" by academic or journalistic sources. These individuals and groups synthesise radical far-right politics with environmentalism, and will typically argue that overpopulation is the primary threat to the environment and that the only solution is a complete halt to immigration or, at their most extreme, genocide against minority groups and ethnicities. Many far-right political parties have added green politics to their platforms. Through the 2010s ecofascism has seen increasing support.

Neither democracy nor the market economy will have the credibility to survive an environmental breakdown. The most likely short-term reaction will be eco-fascism -- an attempt by well-off minorities to protect their privileged access to environmental resources. This will not work, as there is no way of completely excluding the poor from access to the global environment. An "eco-Stalinist" revolution is likely to follow introducing a dictatorship with strict rationing of resources.
