Marinus Lambertus van den Boezem (born 28 January 1934) is a Dutch artist. He is known for his radical view of art and his works in public space. Together with Wim T. Schippers, Ger van Elk and Jan Dibbets, Boezem is seen as one of the main representatives of conceptual art and arte povera in the Netherlands in the late 1960s.
