Far-right politics, also referred to as the extreme right or right-wing extremism, are political beliefs and actions further to the right of the left–right political spectrum than the standard political right, particularly in terms of being radically conservative, ultra-nationalist, and authoritarian, as well as having nativist ideologies and tendencies.

Historically, "far-right politics" has been used to describe the experiences of fascism, Nazism, and Falangism. Contemporary definitions now include neo-fascism, neo-Nazism, the Third Position, the alt-right, racial supremacism, National Bolshevism and other ideologies or organizations that feature aspects of authoritarian, ultra-nationalist, chauvinist, xenophobic, theocratic, racist, homophobic, transphobic, and/or reactionary views.

Far-right politics have led to oppression, political violence, forced assimilation, ethnic cleansing, and genocide against groups of people based on their supposed inferiority or their perceived threat to the native ethnic group, nation, state, national religion, dominant culture, or conservative social institutions.
