Constantin Kirițescu (September 3, 1876 – August 12, 1965) was a Romanian zoologist, educator and historian. Born and schooled in Bucharest, he occupied successive posts in the Education Ministry, with education being a running theme of his diverse interests. He was among the founders of the Romanian Academy of Sciences.
His name is most associated with Istoria războiului pentru reîntregirea României ("The History of the War That United Romania"), a 1922 account of the part played by Romania in World War I.
