Esther Marjorie Hill (May 29, 1895 – January 7, 1985) was a Canadian architect and the first woman to graduate in architecture from the University of Toronto (1920).

Upon graduation Hill was only able to find one job opportunity: as an interior designer at Eaton's department store.

In 1920 and 1921 she authored a series of articles in the journal Agricultural Alberta, describing her functional approach to domestic architecture and her belief in designing to allow in as much natural light as possible.

She went to New York City and studied at Columbia University, apprenticing under Anna Schenck, Marcia Mead, and Katharine Budd.

She moved to Victoria, British Columbia in 1936 with her parents, and after World War II she founded her own architectural firm.

Working out of her parents' home, drafting designs on their dining room table, she became an independent architect in Victoria, until her retirement in 1963.
