Neo-Marxism is a Marxist school of thought encompassing 20th-century approaches that amend or extend Marxism and Marxist theory, typically by incorporating elements from other intellectual traditions such as critical theory, psychoanalysis, or existentialism (in the case of Jean-Paul Sartre).

As with many uses of the prefix neo-, some theorists and groups who are designated as neo-Marxists have attempted to supplement the perceived deficiencies of orthodox Marxism or dialectical materialism. Many prominent neo-Marxists, such as Herbert Marcuse and other members of the Frankfurt School, have historically been sociologists and psychologists.

Neo-Marxism comes under the broader framework of the New Left. In a sociological sense, neo-Marxism adds Max Weber's broader understanding of social inequality, such as status and power, to Marxist philosophy. Examples of neo-Marxism include analytical Marxism, French structural Marxism, critical theory, cultural studies, as well as some forms of feminism. Erik Olin Wright's theory of contradictory class locations is an example of the syncretism found in neo-Marxist thought, as it incorporates Weberian sociology, critical criminology, and anarchism.[1]
