Emilio Ambasz (born 13 June 1943, Resistencia, Chaco) is an Argentine architect and award-winning industrial designer. From 1970 to 1976 he was Curator of Design at the Museum of Modern Art, in New York. Ambasz was an early proponent of 'green' architecture.
Ambasz's trademark style is a combination of buildings and gardens, which he describes as 'green over grey'. He bucked the trends of the 1970s, hiding his buildings under grass or putting them on boats.
The Emilio Ambasz Award for Green Architecture is awarded every year by the Architecture Israel Quarterly magazine.
