John W. Hight, 65 retired executive director of the Committee for a national Trade Policy, died Tuesday at Sibley Memorial Hospital. He had emphysema.

He became executive secretary of the committee, an organization that seeks less restrictive trade barriers between nations, in 1958. He retired for reasons of health in 1972.

Mr. Hight came to Washington during World War II. After working for the War Production Board, he served as an army infantryman in France.

Following the war, he was an economic adviser to the chief of the United Nations Relief and Rehabilitation Administration mission in Rome. From 1948 to 1954, he worked in Paris as a director of the old Economic Cooperation Administration.

Mr. Hight also had been a delegate to both the Trade Committee of the Office of European Economic Cooperation (OEEC), and several GATT tariff negotiating sessions.

He was president of Electrex Corp., a Washington company engaged in the export of wire and cable, for three years before being named executive director of the National Trade Policy committee.

Mr. Hight was a native of Chicago and a 1937 graduate of the University of Chicago.

He is survived by his wife, Betty, and a daughter, Barbara, both of the home in Washington; another daughter, Marny Furbish, of Denver; a son, John C., of Wheaton; his mother, Olive Hight, and a sister, Ruth Corrigan, both of Tulsa, Okla., and three other sisters, Jane Tapp, of Sheboygan, Wis., Muriel O'Neil, of New York City, and Dr. Gertrude Hight, of Philadelphia.

The family suggests that expressions of sympathy be in the form of contributions to the St. Francis Burial and Counseling Society, 1768 Church Street NW. CAPTION: Picture, JOHN W. HIGHT
