William Franklin Draper (April 9, 1842 – January 28, 1910) was an American businessman, industrialist, and soldier who served as a U.S. Representative from Massachusetts.

During the American Civil War Draper enlisted as a private in the Twenty-fifth Regiment, Massachusetts Volunteer Infantry, on September 9, 1861. He was soon elected Second Lieutenant of his company and was promoted rapidly to lieutenant colonel. After his discharge Draper was awarded the brevet grades of colonel and brigadier general of Volunteers.
After the war he joined his family's textile machine manufacturing business at Hopedale, Massachusetts, and patented many improvements. He also served as delegate to the Republican National Convention in 1876. He went on to serve as colonel on the staff of Governor John Davis Long from 1880 to 1883.
Draper was elected as a Republican to the Fifty-third and Fifty-fourth Congresses (March 4, 1893 – March 3, 1897).
