This is a complete list of individuals who have served as president pro tempore of the Idaho Senate to the present. The president pro tempore, often abbreviated to "the pro tem", is a senator chosen from the majority party and elected by the entire Senate. The senator occupying this position will preside over the Senate in the absence of the lieutenant governor or will assign another senator to preside in his stead. When the pro tem or his designee presides over the Senate, they maintain their ability to vote on all matters before the Senate, whereas the lieutenant governor only has a vote in the case of tie.

The pro tem is also second in line in succession to the governor. When both the governor and lieutenant governor are out of the state the pro tem serves temporarily as acting governor until their return. When a vacancy arises in the office of lieutenant governor the pro tem serves as acting lieutenant governor until governor appoints and the Senate confirms a successor. The pro tem is also the leader of the majority party. The office has both administrative and policy roles, though the bulk of work on the Senate floor is largely delegated to the majority leadership.
