Dimitri Dimakopoulos CQ RCA (14 September 1929 – 7 November 1995) was a Greek-Canadian architect. He was best known for having been involved in the design of several notable buildings in Downtown Montreal.^[1]

Dimakopoulos was born in Athens, Greece, on September 14, 1929. He grew up in Athens before emigrating to Montreal, Quebec, Canada, in 1948. He continued his education at the School of Architecture at McGill University. During this period, he earned awards from Anglin Norcross and Hobbs Glass and designed several theatres and concert halls. As the final work during his studies, Dimakopoulos designed the foundations of the Queen Elizabeth Auditorium in Vancouver, British Columbia, in 1954.

In 1955, he participated in the creation of the Affleck, Desbarats, Dimakopoulos, Lebensold, Michaud & Sise architecture firm, which changed names in 1970 to become ARCOP (Architects in Co-Partnership). This firm worked with Henry N. Cobb and Ieoh Ming Pei on the design of Place Ville-Marie, a landmark skyscraper in Downtown Montreal. The firm later worked on other major projects in Quebec and the rest of Canada, including Expo 67, Place Bonaventure in Montreal, and the National Arts Centre in Ottawa, Ontario.

In 1968, he created a new firm, "Dimakopoulos & Associates". The firm designed projects in Quebec City, Gatineau, Winnipeg and Hong Kong. From 1991 to 1992, alongside Lemay & Associates, Dimakopoulos & Associates designed 1000 de La Gauchetière, the tallest building in Montreal.
