Lorentz Harboe Ree (12 March 1888– 8 March 1962) was a Norwegian architect.
Ree was born at Stange in Hedmark, Norway. He graduated from the Norwegian Institute of Technology in 1915. He first worked as an architectural assistant in Bergen (1916-17). He had his own architectural firm in Kristiania (now Oslo) from 1918. He worked together with Harald Aars (1875–1945) from 1919 and from 1920 with Carl Emil Buch (1892-1968).
Most of the buildings he designed were raised in the Oslo districts of Frogner and St. Hanshaugen as well as the neighborhood of Bislett. His style was often in neo-baroque, although he also preferred neo-classic style. His main work was the Vigeland Museum (Vigeland-museet) for which he was awarded the Houens fonds diplom together with Carl Buch in 1926.
