Ernest Willard Gibson (1872–1940) was an American politician and lawyer from Vermont. He served in office in Vermont at the state level and in his later life was elected to the US House of Representatives, from 1923–1933, and Senate, from 1933 until his death in office in 1940. Gibson was a leader of Vermont’s Progressive movement. Gibson was in the US military, including service in World War I as a captain of Company I, 1st Vermont Infantry, which was federalized as the 57th Pioneer Infantry Regiment. The 57th shipped to France during the 1918 influenza pandemic; the Armistice happened before Gibson and surviving regiment members saw combat.
