Peter Cook (born 1936) is a British architect, educator, and writer known for his visionary and avant-garde contributions to architecture. As a co-founder of the influential group Archigram in the 1960s, he challenged conventional architectural thinking with radical, futuristic concepts that continue to inspire experimental design. Beyond theory, Cook has significantly influenced education, serving as Director of the Institute of Contemporary Arts in London (1970–1972) and chairing the Bartlett School of Architecture at University College London (1990–2006). His notable built work includes the Kunsthaus Graz in Austria, designed with Colin Fournier. In recognition of his contributions, he was knighted in 2007.
