Mille-Marie Treschow (born 3 April 1954 in Larvik, Vestfold) is a Norwegian landlord and businessperson. Treschow belongs to the Danish and Norwegian noble family of Treschow.

Mille-Marie Treschow is the daughter of estate owner Gerhard Aage Treschow (1923–2001) and Nanna, née Meidell (born 1926). Her name partly reflects that of her then-recently deceased aunt, Marie Treschow (1913-1952), who was paralyzed in a 1933 diving accident but then became a Scandinavian philanthropist and subject of a biography by Eivind Berggrav.

She has married three times and is currently separated. She has two children born of her second marriage (1984–2000), with Andreas Stang. In 2004 she married businessman Stein Erik Hagen. In 2012 they announced their separation.

Mille-Marie Treschow has been a pupil at Croft House School in Dorset, England. She has also Norwegian examen artium. She received a Master of Business Administration in Switzerland, and she has additionally economic studies from the United States of America and home economics studies from France.

Based in Larvik, Treschow manages —Treschow Fritzøe— an extensive consortium consisting of properties and forest as well as industry, trade, and other enterprises. She owns a private estate and resides at Fritzøehus Manor in Larvik. Succeeding her father in 1986, she is the 6th generation owning and running the family industry.

Treschow has an estimated private fortune of 1.5 billion Norwegian kroner (NOK) or about $250 million USD. She is as such one of the wealthiest women in Norway. Her husband Stein Erik Hagen is considered being worth about 10 billion NOK or about $2 billion USD.
