The 2018 election for lieutenant governor of Idaho took place on November 6, 2018. The primary election to select the candidates from each party to run in the general election took place on May 15, 2018. Lieutenant governors serve a four-year term or terms. In 2018, the incumbent lieutenant governor, Brad Little, won the Republican nomination for governor and declined to run for re-election in order to run for governor.

Far-right former state representative Janice McGeachin won the election in a landslide, defeating Democrat Kristin Collum. After one term, she retired in 2022 to run unsuccessfully for Governor.

Campaign On March 3, 2018, Bob Nonini reportedly nodded when asked at a candidates' forum if the punishment for getting an abortion should include the death penalty. However, he denied ever having nodded in agreement. "Prosecutions have always been focused on the abortionist," he said later, but such a law and "...the threat of prosecution, would dramatically reduce abortion. That is my goal."
