Peter Eisenman (Newark "Newark (New Jersey)", New Jersey, August 11, 1932) is an American architect, writer and university professor. A member of the New York Five, he is known for his works of fragmented and overlapping forms, as well as for being the author of several books on architecture.

Internationally recognized for his willingness to question the very foundations of architecture, he has carried out everything from single-family homes to large-scale projects such as the Berlin Holocaust Memorial, the State Farm Stadium in Glendale, Arizona "Glendale (Arizona)"), or the Galician City of Culture in Santiago de Compostela.

He was born into a family of German Jewish immigrants from Strasbourg on August 11, 1932 in Newark, New Jersey. He earned a bachelor's degree in architecture from Cornell University, a master's degree from Columbia University, and an MFA and PhD from the University of Cambridge.

He came to prominence as a member of the New York Five, along with his fellow architects Charles Gwathmey, John Hejduk, Richard Meier and Michael Graves, thanks to a series of conferences organized by the Committee of Architects for the Study of the Environment (CASE) at the Museum of Modern Art in New York. The proposals of this group were characterized by taking up elements of the rationalist architecture "Rationalism (architecture)") of the 1920s and 1930s - especially the work of Le Corbusier - although they rejected the principle of "form follows function", defending the autonomy of the architectural form.

Over time each of the members evolved differently. The expansive, fragmentary and unconnected aspects of Eisenman's work led him to be considered one of the first deconstructivist, a label from which he always wanted to distance himself.[1]​.

As a result of the ideas competition he won, he built the Galician City of Culture in Santiago de Compostela, a set of buildings intended for cultural activities. Some works that modified John Hejduk's original design of the city and led him to collaborate with the Spanish architects Andrés Perea and Andrés Jaque. The works have been the subject of public controversy due to their economic management and doubts about their subsequent usefulness.

In 2008, a book was published about his work that develops the temporary installations he has made: Installations: About the Work of Peter Eisenman, by Pablo Lorenzo-Eiroa, DLO/Robles Ediciones, Buenos Aires, 2008.
