Moshe Safdie (born July 14, 1938) is an architect and urban planner. He was born in Haifa, Israel, but he moved with his family to Montreal, Canada when he was 15 years old. He was trained as an architect at McGill University in Montreal from 1955 to 1961. He started his career at the office of Louis I. Kahn where he worked for zwo years. Subsequently, he started his own practice in Montreal. In 1967, he returned to Israel, where he was part of the team that refurnished Old Jerusalem.

In 1978, he became Director of the Urban Design Program and the Ian Woodner Professor of Architecture and Urban Design at the Harvard University Graduate School of Design. His company, Moshe Safdie and Associates, Inc. is based out of Somerville, Massachusetts with branch offices in Toronto and Jerusalem.

Influenced by his graduate thesis, Safdie refined a series of "Habitat" designs which revolved around a cellular housing scheme. Initially his ideas proved expensive and difficult to construct, but Safdie introduced the cellular scheme in several areas including New York and Puerto Rico where his ideas were successfully initiated.

His Israeli period also produced a number of impressive urban insertion projects and various town-planning schemes.
