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.
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.
