The 1916 United States Senate elections were elections that coincided with the re-election of President Woodrow Wilson. This was the first election since the enactment of the Seventeenth Amendment that all 32 Class 1 senators were selected by direct or popular elections instead of state legislatures. Republicans gained a net of two seats from the Democrats, and then an additional two seats through mid-term vacancies thereby reducing Democrats to a 52–44 majority.

Four Republicans and two Democrats retired instead of seeking re-election.

There were two elections held November 7, 1916, due to a vacancy. The elections converted both seats from Democratic to Republican, thus marking the first time since the popular-election of Senators was mandated by the Seventeenth Amendment three years earlier that both Senate seats in a state flipped from one party to the other in a single election cycle.

The 1916 United States Senate election in Vermont took place on November 7, 1916.^[68] It was the second direct election for the U.S. Senate to take place in Vermont following the ratification of the Seventeenth Amendment to the United States Constitution and the first for Vermont's Class I seat. The incumbent, Republican Carroll S. Page successfully ran for re-election to a second full term.^[69]

In the primary election, which was held on September 11, Page gained re-nomination by winning 62 percent of the vote to defeat former governor Allen M. Fletcher (20.3) and current governor Charles W. Gates (17.7).^[70]

With the Republican Party dominant in Vermont, as it had been since its founding in the 1850s, Democratic candidate Oscar C. Miller was little more than a token opponent for Page.^[71] In the general election, Page defeated Miller 74.4 percent to 23.5.^[69]
