Mi?u Dulgheru (born Mihai Dulberger; January 16, 1909 – April 11, 2002) was a Romanian communist activist and spy.
A clerk by trade, he rose through the secret police as the Romanian Communist Party consolidated its hold on power between 1944 and 1947, while from 1948 through 1952, he played an important role as an officer in the new Securitate.
Subsequently, arrested as part of a wider purge, he was released after an investigation lasting over two years, but never regained his earlier prestige.
Late in life, he left his native country for Israel and, later, Canada.
