Radical centrism, also called the radical center, the radical centre, and the radical middle, is a concept that arose in Western nations in the late 20th century. The radical in the term refers to a willingness on the part of most radical centrists to call for fundamental reform of institutions. The centrism refers to a belief that genuine solutions require realism and pragmatism, not just idealism and emotion.

Centrism is a political outlook or position involving acceptance or support of a balance of social equality and a degree of social hierarchy while opposing political changes that would result in a significant shift of society strongly to the left or the right.
