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.

Humanism is a philosophical stance that emphasizes the individual and social potential, and agency of human beings, whom it considers the starting point for serious moral and philosophical inquiry.
