Mihailo Marković was a Serbian philosopher who gained prominence in the 1960s and 1970s as a proponent of the Praxis School, a Marxist humanist movement that originated in Yugoslavia.

Marxist humanism is an international body of thought and political action rooted in a humanist interpretation of the works of Karl Marx. It is an investigation into "what human nature consists of and what sort of society would be most conducive to human thriving" from a critical perspective rooted in Marxist philosophy. Marxist humanists argue that Marx himself was concerned with investigating similar questions.
