Montrose W. Morris (March 20, 1861 – April 14, 1916) was an American architect from Brooklyn best known for some of the first multi-unit apartment buildings in New York City.

Morris worked in the prevalent architectural styles of the period, including Queen Anne and Romanesque Revival.

In 1876, he became an apprentice to Manhattan architect Charles W. Clinton, who, in concert with his partner, Hamilton Russell, was responsible for some of New York's most iconic buildings, including the Seventh Regiment Armory, the Graham Court Apartments, and the Masonic Temple (now the New York City Center).

He had two sons, Raymond M. and LeRoy C., who worked in his architectural practice starting in 1911; they carried on the firm in their father's name after his early death.

He advertised his services by designing and building his own residence on Hancock Street between Marcy and Tompkins Avenues in the Bedford Stuyvesant district, and then opened it to the public.
