The 1912 Nebraska lieutenant gubernatorial election was held on November 5, 1912, and featured Republican nominee Samuel Roy McKelvie defeating Democratic nominee Herman Diers as well as Socialist Party nominee W. T. Jeffryes and Prohibition Party nominee Theodore J. Shrode.
On May 2, 1911, incumbent Nebraska Lieutenant Governor Melville R. Hopewell died while in office. After the death of Hopewell, John H. Morehead was considered to be the acting lieutenant governor due to his position as president "pro tempore" of the Nebraska Senate based on Article V, Section 18, of the Nebraska Constitution. Morehead decided to seek the office of Governor of Nebraska and thus did not run to be officially elected as lieutenant governor in the election of 1912.
