Peter Roehr (1 September 1944 in Lauenburg in Pommern – 15 August 1968 in Frankfurt am Main) was a German Pop Art minimalist artist.
After visiting the Volksschule he completed an apprenticeship as producer for electronic signage in Frankfurt am Main.
Roehr was in close contact with the artists Charlotte Posenenske and Thomas Bayrle, who lived in Frankfurt as well.
In May 1967 Roehr and Paul Maenz organized in the Studio Galerie of the Goethe University Frankfurt a groundbreaking exhibition entitled Serielle Formationen where works by Carl Andre, Jan Dibbets, Hans Haacke, Donald Judd, Piero Manzoni and Jan Schoonhoven were shown.
Roehrs Oeuvre can be labelled as conceptual art because he aligned each work to the conception of the unvaried repetition.
