Mari Nalte Orensanz (born 12 September 1936) is an Argentine artist. Her artwork examines the integration of thought and matter as a methodology to obtain a social consciousness. Orensanz's experience of Argentina's "Dirty War" has influenced her artwork and translated itself into the work Pensar es un Hecho Revolucionario (Thinking is a Revolutionary Act). Located in the Parque de la Memoria in Bueno Aires, it is attributed as a monument for the victims of state terrorism.
