Donald G. MacIver, 75, a retired hotel and restaurant manager who worked at several establishments in the Washington area, Baltimore, Annapolis and elsewhere, died Friday at Suburban Hospital in Bethesda. He had pulmonary and heart disorders.

Mr. MacIver, was born in Millan, Quebec, Canada, and grew up on a farm in Elm Creek, Manitoba, Canada. He moved to the United States in the mid-1920s and served three years in the Army.

He then began his career in the hotel and restaurant business. He worked at the New Yorker Hotel in New York City and managed the Officer's Club at the Governor's Island Army post in New York harbor during World War II. He also was assistant manager of the Belvedere Hotel in Baltimore, the manager of the Carvel Hall hotel in Annapolis, and then worked in Springfield, Ohio.

In 1958, Mr. MacIver moved to the Washington area and managed the coffee shop at the Sherton Park Hotel here. Subsequently he worked for the International Inn in Washington, managed the food operation at the Western Electric Co. offices in Arlington, and worked for the Charterhouse and then the Travel Lodge motor inn, from which he retired in 1965.

Mr. MacIver was a Mason.

His marriage to the former Elsie Rautenkranz ended in divorce. A son by that marriage, Neil Kirk MacIver, was killed in action in Vietnam in 1963.

Mr. MacIver's survivors include his wife of 23 years, the former Pegge Farmer, of Silver Spring, where the family lived, and three brothers, Alan, of Beamsville, Ontario, Canada; Hector, of Burlington, Ontario, Canada, and Angus, of Winnepeg, Manitoba, Canada.
