Peter Rohs (born 11 January 1936) is a German philosopher.
Born in Jena, Rohs received his doctorate in 1964 from Christian-Albrechts-Universität at Kiel with a thesis on logic by Hegel and habilitated in 1975 at Goethe University in Frankfurt. He was a private lecturer for philosophy since 1975 and from 1985 to 1986 he was managing director of the Forum für Philosophie in Bad Homburg.
Since 1986 Rohs has been teaching as professor at the Philosophy Department of the Westfälische Wilhelms-Universität in Münster. At the centre of his thinking is the systematic project of a field-theoretical transcendental philosophy: he combines a field-theoretical interpretation of nature with a transcendental-philosophical theory of subjectivity. Rohs sees time as a bracket, he refers to the English philosopher John McTaggart Ellis McTaggart.
